(a)
Expert Solution
Answer to Problem 15.1AYK
It is not reasonable to calculate the confidence interval for the percent answering.
Explanation of Solution
Given:
Of the 1290 vote cast, 864 were “yes” response.
In this study, the responses of the question have two options, say, Yes or No. In this poll, it is not mandatory to give responses for the question. This type of survey is called voluntary survey.
It is not reasonable to calculate the confidence interval for the percent answering.
Conclusion:
Therefore, it is not reasonable to calculate the confidence interval for the percent answering.

Answer to Problem 15.1AYK
It is not reasonable to calculate the confidence interval for the percent answering, because it is a voluntary survey.
Explanation of Solution
It is not mandatory for online readers to give responses for the question. It depends upon online readers what to click or whether to click or not.

A physician who has a group of 38 female patients aged 18 to 24 on a special diet wishes to estimate the effect of the diet on total serum cholesterol. For this group, their average serum cholesterol is 188.4 (measured in mg/100mL). Suppose that the total serum cholesterol measurements are normally distributed with standard deviation of 40.7. (a) Find a 95% confidence interval of the mean serum cholesterol of patients on the special diet.
The accompanying data represent the weights (in grams) of a simple random sample of 10 M&M plain candies. Determine the shape of the distribution of weights of M&Ms by drawing a frequency
