As part of a survey, a marketing representative asks a random sample of 29 business owners how much they would be willing to pay for a website for their company. She finds that the sample standard deviation is $3419. Assume the sample is taken from a normally distributed population. Construct 99% confidence intervals for (a) the population variance σ2 and (b) the population standard deviation σ. Interpret the results.

(a) The confidence interval for the population variance is (___,___). (Round to the nearest integer as needed.)

Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to the nearest integer as needed.)

A.With 99% confidence, you can say that the population variance is between ___ and ___.

B.With 1% confidence, you can say that the population variance is greater than ___.

C.With 99% confidence, you can say that the population variance is less than ___.

D.With 1% confidence, you can say that the population variance is between ___ and ___.

Question 2) A marketing research manager intends to survey a simple random sample of Swiss consumers and ask questions about level of beverage consumption. How can she estimate the population standard deviation for this variable before selecting the sample? Why would she need to do that? What would happen if her initial estimate were not reflected in the sample results (i.e., if the estimated standard deviation in the sample turned out to be larger than expected)?
