1. A researcher would like to compare the effectiveness of video versus reading for communicating information to adolescents. A sample of n1= 10 adolescents is given a pamphlet explaining nuclear energy and told that they will be tested on the information. A separate sample of n2= 10 adolescents is shown a video that contains the same information presented in a fast-paced visual form and told that they will be tested. One week later all 20 subjects are given a test on nuclear energy. The average score for the pamphlet group was 1= 51 with s12= 16. The video group averaged 2= 46 with s22= 20. Conduct a t-Test (two-tail, α = .05) for two Independent groups to see if there is a significant difference between the two groups (follow the Handout).
Answer:
There is significant statistical evidence to suggest there is a difference between the groups
Step-by-step explanation:
The number of adolescents in the sample that were given a pamphlet, n₁ = 10
The average score of those given a pamphlet, \(\bar x_1\) = 51
s₁² = 16
The number of adolescents in the sample that were given a video, n₂ = 10
The average score of those given a video, \(\bar x_2\) = 46
s₂² = 20
The alpha level of the test, α = 0.05
H₀ = No difference
Hₐ = Difference between the groups
The test statistic for the difference in mean is given as follows;
\(t=\dfrac{(\bar{x}_1-\bar{x}_{2})}{\sqrt{\dfrac{s_{p}^{2} }{n_{1}}+\dfrac{s _{p}^{2}}{n_{2}}}}\)
Plugging in the values, gives;
\(t=\dfrac{(46-55)}{\sqrt{\dfrac{18 }{10}+\dfrac{18}{10}}} \approx -4.73\)
The degrees of freedom, n₁ + n₂ - 2 = 20 - 2 = 18
The critical-t = 2.101
Therefore
Given that the test statistic is larger than than the critical-t, we reject the null hypothesis that there is no difference

The acceleration will be 2.1 meters per second. The correct option is A.
What is acceleration?Acceleration of any object is defined as the variation in the speed of the object with the variation of the time. Acceleration is a vector term and to define it we require both the magnitude and the direction. The unit of the acceleration can be m / sec², miles / sec², etc.
Given that a car accelerates along a straight road, which is 15km long. The car reaches a speed of 75 km/h in 10s.
The acceleration will be calculated as below:-
Acceleration = Velocity / Time
Velocity = 75 km / h = 75 x ( 5 / 18 ) = 20.83 m / s
Acceleration = Velocity / Time
Acceleration = 20.83 / 10 = 2.08 or 2.1 m / s²
Therefore, the acceleration will be 2.1 meters per second. The correct option is A.

Options: 127, 81, 19, 13
The distance from home plate to second base is 90\(\sqrt{2}\) ≈ 127.3 feet so option 1 is correct.
Given :
A baseball diamond is square.
The distance from home plate to first base is 90 feet which is nothing but side of square.
Let x be the distance from home plate to second plate.
we need to find home plate to second plate distance which is nothing but diagonal of square.
with 2 sides of length 90 feet and one diagonal forms a right angled triangle.
According to pythagorean theory:
\(90^{2}\) + \(90^{2}\) = \(X^{2}\)
\(X^{2}\) = 8100 + 8100
\(X^{2}\) = 16200

lou gehrig's disease is autosomal recessive disease. if a woman and her husband are both carriers, what is the probability that their first child will be a phenotypically normal girl?
The probability that their first child will be a phenotypically normal girl is 3/8 or 37.5%.
Lou Gehrig's disease, also known as amyotrophic lateral sclerosis (ALS), is typically considered as an autosomal recessive disease. This means that both copies of the gene responsible for the disease need to be inherited, one from each parent, in order for an individual to be affected by the disease.
Given that the woman and her husband are both carriers of the disease, they each have one copy of the mutated gene and one normal gene. The probability of passing on the mutated gene to their child is 1/2 for each parent since they are carriers.
To determine the probability of their first child being a phenotypically normal girl, we need to consider the inheritance pattern. Let's break it down:
Gender: The probability of having a girl is 1/2, as gender is determined by the combination of the father's sperm (containing either an X or a Y chromosome) and the mother's egg (containing an X chromosome).
Phenotypically normal: For the child to be phenotypically normal, they should inherit at least one normal gene from either parent. The probability of inheriting a normal gene from the mother is 1/2, and the same probability applies for inheriting a normal gene from the father.
Independence: The probability of having a girl and inheriting a normal gene are independent events, so we can multiply their individual probabilities to calculate the combined probability.
Therefore, the probability of having a phenotypically normal girl is:
Probability of being a girl × Probability of inheriting a normal gene
= (1/2) × (1/2)
= 1/4
However, we also need to consider the possibility of having a boy. The probability of having a phenotypically normal boy is also 1/4.
Adding the probabilities of having a phenotypically normal girl and a phenotypically normal boy, we get:
1/4 + 1/4 = 2/4 = 1/2
Since the question specifically asks for the probability of having a phenotypically normal girl, we divide the probability of a phenotypically normal girl by the total probability of having a child:
(1/4) / (1/2) = 1/4 * 2/1 = 1/2 = 2/4 = 1/2
Therefore, the probability that their first child will be a phenotypically normal girl is 1/2 or 50%.

Which of the following factors does NOT control the stability of a slope?
the angle of repose for intact bedrock
whether the slope is rock or soil
the amount of water in the soil
the orientation of fractures, cleavage, and bedding
The factor that does NOT control the stability of a slope is the angle of repose for intact bedrock. The angle of repose refers to the steepest angle at which a pile of loose material remains stable without sliding. It is mainly applicable to loose materials like soil and granular substances, not intact bedrock.
Bedrock stability depends on factors such as its strength, fracturing, and geological properties, rather than the angle of repose. Factors that control the stability of a slope include whether the slope is rock or soil. Rock slopes tend to be more stable than soil slopes due to the cohesive nature of intact rock.
The amount of water in the soil also affects slope stability, as excessive water can increase pore pressure and reduce the shear strength of the soil, leading to slope failure. Additionally, the orientation of fractures, cleavage, and bedding in the rock can influence slope stability by creating planes of weakness or strength.
To summarize, while the angle of repose is a significant factor in slope stability, it is not applicable to intact bedrock. The stability of a slope is influenced by the type of material (rock or soil), the presence of water, and the orientation of fractures and bedding.

There are 240 different ways to paint a cube such that one side is blue, two sides are red and three sides are green.
In the given problem, we can imagine the different possible configurations for painting different sides of a cube. We can consider the number of cubes that would be painted with one blue face, two red faces, and three green faces. In total, we could paint any of the six faces with blue, any of the remaining five faces with red, and any of the remaining four faces with green.
Therefore, the total number of different cubes that can be painted with one blue face, two red faces and three green faces is the product of the number of ways to choose one blue face from the six faces, times the number of ways to choose two red faces from the remaining five faces, times the number of ways to choose three green faces from the remaining four faces.

Patrick won a sweepstakes and will receive money each week for 52 weeks. The first week he will receive $10. Every week after that he will receive 10% more than he got the previous week. How much money did he receive over the 52 weeks?
Patrick received a total of approximately $6,785.97 over the course of 52 weeks.
To calculate the total amount of money Patrick received over the 52 weeks, we can use the concept of a geometric sequence. The first term of the sequence is $10, and each subsequent term is 10% more than the previous term.
To find the sum of a geometric sequence, we can use the formula:
Sn = a * (r^n - 1) / (r - 1),
where Sn is the sum of the first n terms, a is the first term, r is the common ratio, and n is the number of terms.
In this case, a = $10, r = 1 + 10% = 1.1 (common ratio), and n = 52 (number of weeks).
Plugging these values into the formula, we can calculate the sum of the sequence:
S52 = 10 * (1.1^52 - 1) / (1.1 - 1)
After evaluating this expression, we find that Patrick received approximately $6,785.97 over the 52 weeks.

A certain factory manufactures parts with an unknown defect rate of p. Inspectors take a small sample of parts and find a total of 2 defective parts and 8 working parts.
(a) What is the Beta distribution that you would use to model p, the true defect rate?
(b) Using the distribution you found, find P(.15 ≤p ≤.25).
(c) The inspectors take another sample. In this sample, they find 1 defective part and 9 working parts. Combining this sample with the previous inspection, what is the new Beta distribution that you would use to model p?
(d) Repeat part (b) for this new Beta distribution.
(a) The Beta distribution that is commonly used to model the true defect rate p is the Beta-Binomial distribution.
It is a combination of the Beta distribution, which represents the uncertainty in the true defect rate, and the Binomial distribution, which represents the number of defectives in a fixed sample size. The parameters of the Beta distribution, α and β, determine the shape of the distribution and can be estimated based on the observed data.
(b) To find P(0.15 ≤ p ≤ 0.25), we need to calculate the cumulative distribution function (CDF) of the Beta distribution with the given parameters α and β. The CDF represents the probability that the true defect rate is less than or equal to a certain value. By evaluating the CDF at p = 0.25 and subtracting the CDF at p = 0.15 from it, we can obtain the desired probability.
(c) When combining the two samples, the new Beta distribution for modeling p can be obtained by updating the parameters α and β based on the additional observations. In this case, with a total of 3 defective parts and 17 working parts (2 + 1 defective and 8 + 9 working), we can calculate the new values of α and β.
(d) Similar to part (b), we can use the updated parameters of the Beta distribution to calculate the probability P(0.15 ≤ p ≤ 0.25) for the new distribution. By evaluating the CDF of the updated Beta distribution at p = 0.25 and subtracting the CDF at p = 0.15 from it, we can determine the probability of the true defect rate falling within the specified range.

Step-by-step explanation: how i always do it is the second number (-2) you start for the mid point (0,0) if its -2 go down 2 if it 2 go up 2 if its 0 stay there then you go to the first number(2/3) from where you landed thats now the new start point then you go (x,y) in this equation its (2/3) so go up 2 right three but watch out for the negatives. so if it was -2/3 you would go down 2 then right 3
i hoped this helped its hard to explain but I tried
