A consumer group selected 100 different airplanes at random from each of two large airlines. the mean seat width for the 100 airplanes was calculated for each airline, and the difference in the sample mean widths was calculated. the group used the sample results to construct a 95 percent confidence interval for the difference in population mean widths of seats between the two airlines.
Answers
Decreasing the sample size decreases the width of the confidence interval.
What is mean?The arithmetic mean, also known as the arithmetic average or simply the mean or average, is the sum of a set of numbers divided by the total number of numbers in the set. The collection frequently consists of a series of findings from a survey, experiment, or observational study.
Let,
s = sample standard deviation
X ± \(1.96X\frac{s}{\sqrt[2]{100}}\)
X ± 0.1960s
Similarly, for n = 50,
X ± 0.2772s.
Thus, it can be concluded that decreasing the sample size decreases the width of the confidence interval.

How the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of moecules and atoms involved
Answers
The chemical equation for cellular respiration shows that plants cycle matter because through cellular respiration, plants take in carbon dioxide from the atmosphere, use it to produce glucose through photosynthesis, and then release the carbon dioxide back into the atmosphere through respiration.
Here is the process of cellular respirationThe chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (ATP)
The above equation shows how plants, as well as other organisms, cycle matter through the process of respiration. In this equation, glucose (C6H12O6) is combined with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O), releasing energy in the form of ATP.
The numbers of molecules and atoms involved in this equation are:
1 molecule of glucose (C6H12O6)6 molecules of oxygen (O2)6 molecules of carbon dioxide (CO2)6 molecules of water (H2O)Breaking down the molecules further, we can see that the equation involves:
6 carbon atoms12 hydrogen atoms18 oxygen atomsThrough cellular respiration, plants take in carbon dioxide from the atmosphere, use it to produce glucose through photosynthesis, and then release the carbon dioxide back into the atmosphere through respiration. Water is also cycled through the process, as it is used in photosynthesis and produced as a byproduct of respiration. Overall, cellular respiration plays a crucial role in the carbon and water cycles of our planet, helping to maintain the balance of these essential resources.

While Jenner's interest in the protective effects of cowpox began during his apprenticeship with George Harwicke, it was 1796 before he made the first step in the long process whereby smallpox, the scourge of mankind, would be totally eradicated. For many years, he had heard the tales that dairymaids were protected from smallpox naturally after having suffered from cowpox.

Smallpox and Vaccination,"
Stefan Riedel
Which statements support the claim that Jenner has been given credit for starting and spreading the practice of immunization?
Jenner became interested in the protective effects of cowpox during his apprenticeship.
Jenner’s mentor was George Harwicke.
Jenner made the first step to erase smallpox.
Smallpox is called the scourge of mankind.
Jenner heard stories of cowpox helping to save people from smallpox.
Answers
These statements show that Jenner was the one who took the first step towards eradicating smallpox by investigating the link between cowpox and smallpox immunity. Additionally, the fact that he had heard stories of cowpox protecting people from smallpox suggests that he was the one who popularized the idea of using cowpox as a means of immunization. However, the statements about Jenner's apprenticeship, mentor, and the severity of smallpox are not directly related to his contribution to the practice of immunization.

Find the probability of getting 6 or more girls in 8 births.
Answers
Answer:
The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.
Explanation:
Answer:
Explanation:
P(X > 6) = ?
P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)
P(X > 6) = 0.118 + 0.035 + 0.004
P(X > 6) = 0.157
Thus the probability of getting 6 or more girls in 8 births is 0.157

what fallacy is assuming, without further evidence, that something cause what happened after it?
Answers
Answer:
Slippery Slope
Explanation:
The Latin phrase "post hoc, ergo propter hoc" means "after this, therefore because of this," and it refers to the fallacy you are discussing. Additionally, it is occasionally referred to as the "post hoc fallacy."
The logical fallacy in a post hoc argument is the assumption that something causes another thing simply because they happen one after the other. The adage "correlation does not imply causation" is frequently used.
When two events occur in close proximity to one another, this is known as correlation. They might be connected, but it could also just be a coincidence.
It is impossible to determine if one led to the other or even if they are indeed connected. This error is frequently made by those who believe that because something occurs after another, it must have a logical cause.

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answers
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.

Read the paragraph from The Hot Zone.
She took up a scalpel and slit the monkey's abdomen, making a slow and gentle cut, keeping the blade well away from her gloved fingers. The spleen was puffed up and tough, leathery, like a globe of smoked salami. She did not see any bloody lesions inside this monkey. She had expected that the monkey's interior would be a lake of blood, but no, this monkey looked all right, it had not bled into itself. If the animal had died of Ebola, this was not a clear case. She opened up the intestine. There was no blood inside it. The gut looked okay. Then she examined the stomach. There she found a ring of bleeding spots at the junction between the stomach and the small intestine. This could be a sign of Ebola, but it was not a clear sign. It could also be a sign of simian fever, not Ebola. Therefore, she could not confirm the presence of Ebola virus in this animal based on a visual inspection of the internal organs during necropsy.
Which statement best summarizes the central idea of this paragraph?

b. Performing a necropsy is a tedious procedure.
