Answer:

a) Because the confidence interval  does not include  0​ it appears that there

is  a significant difference between the mean level of hemoglobin in women and the mean level of hemoglobin in men.

b)There is​ 95% confidence that the interval from  −1.76 g/dL<μ1−μ2<−1.62 g/dL actually contains the value of the difference between the two population means μ1−μ2

c)   1.62 < μ1−μ2< 1.76

Step-by-step explanation:

a) What does the confidence interval suggest about equality of the mean hemoglobin level in women and the mean hemoglobin level in​ men?

Given:

95% confidence interval for the difference between the two population​ means:

−1.76g/dL< μ1−μ2 < −1.62g/dL

population 1 =  measures from women

population 2 =  measures from men

Solution:

a)

The given confidence interval has upper and lower bound of 1-62 and -1.76. This confidence interval does not contain 0. This shows that the population means difference is not likely to be 0. Thus the confidence interval implies that the mean hemoglobin level in women and the mean hemoglobin level in​ men is not equal and that the  women are likely to have less hemoglobin than men. This depicts that there is significant difference between mean hemoglobin level in women and the mean hemoglobin level in​ men.

b)  

There is​ 95% confidence that the interval −1.76 g/dL<μ1−μ2<−1.62 g/dL actually contains the value of the difference between the two population means μ1−μ2.

c)

If we interchange men and women then

                                          1.62 g/dL<μ1−μ2<1.76 g/dL.

There is a significant difference between the mean level of hemoglobin in women and in men.

The confidence interval of the mean is given as:

\(-1.76 g/dL < \mu_1-\mu_2 < -1.62 g/dL\)

The above confidence interval shows that the confidence interval is exclusive of 0.

This means that 0 is not part of the confidence interval

Since the confidence interval is exclusive of 0, then there is a significant difference between the mean level of hemoglobin in women and in men.

The minimum sample size required when you want to be 99% confident that the sample mean is within one unit of the population mean and σ = 13.8 is 1268

Given: To find the minimum sample size, confidence level = 99%, standard deviation = 13.8, and one unit population mean. [Normally distributed]

Solving the given question:

We know that the formula for Margin of error is:

Margin of error = z-score * (standard deviation) / root (sample size)

E = z * σ / √(n), where

E = Margin of error

z = z-score

n = Sample size

σ = standard deviation

Therefore, sample size = ( z – score * standard deviation / margin of error)²

n = ( z * σ / E )²

First, calculate the z-score for the 99% confidence level.

From the normal distribution curve, the area under 99% confidence level is given as:

Area under 99% confidence level = (1 + confidence level) / 2 = (1 + 0.99) / 2 = 0.995

From the z-score table, we find the value of z with the corresponding area of 0.995

We find the value of the z-score corresponding to 0.995 is 2.58

Also given sample mean is one unit of the population. So the margin of error is 1

E = 1

And given Standard deviation = 13.8

σ = 13.8

Putting the values in the given formula of sample size n =

n = (2.58 * 13.8 / 1 )²

n = 1267.64

n = 1268

Hence the minimum sample size required when you want to be 99% confident that the sample mean is within one unit of the population mean and σ = 13.8 is 1268

Answer:

x = 10

Step-by-step explanation:

Assuming that the triangles are similar we can use ratios to solve for x.

x / 6 = 35 / 21

Using cross products we acquire,

35 * 6 = 210

21 * x = 21x

21x = 210

Divide both sides by 21

21x/21=x

210/21=10

x = 10

No, the current optimal solution may not remain optimal.

To determine if the current optimal solution remains optimal after adding a new variable x3, we need to examine the relation between primal optimality and dual feasibility.

In the primal LP, the current optimal tableau indicates that the artificial variables a1 and a2 are present in the basis. This suggests that the original problem is infeasible. The presence of artificial variables in the basis indicates that the original problem had no feasible solution. Thus, the current optimal solution is not valid.

When we add a new variable x3 and modify the primal LP accordingly, we need to solve the modified LP to determine the new optimal solution. The modified LP has a different constraint and objective function, which can lead to different optimal solutions compared to the original LP.

Therefore, the current optimal solution may not remain optimal when we add a new variable and modify the primal LP.

To determine whether the sequence {an} = 5n/4n + 1 is convergent or divergent, we can analyze its behavior as n approaches infinity.

First, let's rewrite the expression for the nth term of the sequence:

an = 5n / (4n + 1)

As n approaches infinity, the denominator 4n + 1 becomes dominant compared to the numerator 5n. Therefore, we can simplify the expression by neglecting the term 5n:

an ≈ n / (4n + 1)

Now, we can consider the limit of the sequence as n approaches infinity:

lim(n→∞) n / (4n + 1)

To evaluate this limit, we can divide both the numerator and denominator by n:

lim(n→∞) (1 / 4 + 1/n)

As n approaches infinity, the term 1/n approaches zero, leaving us with:

lim(n→∞) 1 / 4 = 1/4

Since the limit of the sequence is a finite value (1/4), we can conclude that the sequence {an} = 5n/4n + 1 is convergent.

In other words, as n gets larger and larger, the terms of the sequence {an} get closer and closer to the limit of 1/4. This indicates that the sequence approaches a fixed value and does not exhibit wild oscillations or diverge to infinity. Therefore, we can say that the sequence is convergent.

Step-by-step explanation:

The approximate volume of the cone with a radius of 1.75 feet and a height of 2.1 feet is approximately 6.478875 cubic feet.

To calculate the approximate volume of a cone, you can use the formula:

Volume = (1/3) * π * r^2 * h,

where r represents the radius of the cone's base and h represents the height of the cone.

Given that the radius (r) is 1.75 feet and the height (h) is 2.1 feet, we can substitute these values into the formula:

Volume = (1/3) * π * (1.75)^2 * 2.1

To calculate the approximate volume, we'll use the value of π as approximately 3.14:

Volume ≈ (1/3) * 3.14 * (1.75)^2 * 2.1

Now, we can perform the calculations:

Volume ≈ (1/3) * 3.14 * 3.0625 * 2.1

≈ 1.047 * 3.0625 * 2.1

≈ 6.478875

Therefore, the approximate volume of the cone with a radius of 1.75 feet and a height of 2.1 feet is approximately 6.478875 cubic feet.

If two variables have a positive correlation coefficient, larger values of one variable are associated with larger values of the other. (Option 2)

A correlation coefficient measures the strength and direction of the linear relationship between two variables. A positive correlation coefficient indicates that as the values of one variable increase, the values of the other variable also tend to increase. Similarly, as the values of one variable decrease, the values of the other variable also tend to decrease.

Therefore, if two variables have a positive correlation coefficient, larger values of one variable are associated with larger values of the other. Conversely, smaller values of one variable are associated with smaller values of the other. This means that the variables are not independent from each other and that they tend to move together in the same direction.

$962140.64 much will Jansen's mortgage payment be for the condo. This can be solved using the concept of simple interest.

For the usage of money, a lender will charge a borrower interest. It indicates the expense of borrowing money and is often represented as a percentage of the loan amount. The principle of the loan, the interest rate, and the duration of the loan term are used to compute interest, which is paid over time.

Compound interest and simple interest are the two major forms of interest. Simple interest is computed just on the loan's principal, whereas compound interest is calculated on the principal as well as the interest that has accrued over time. Compared to simple interest, compound interest causes the loan debt to increase more quickly.

Given that,
