As part of a survey, a marketing representative asks a random sample of 27 business owners how much they would be willing to pay for a website for their company. She
finds that the sample standard deviation is $3599. Assume the sample is taken from a normally distributed population. Construct
95% confidence intervals for (a) the
population variance 2 and (b) the population standard deviation a. Interpret the results.
(a) The confidence interval for the population variance is (☐☐).
(Round to the nearest integer as needed.)
