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 $3376. Assume the sample is taken from a normally distributed population. Construct 90% confidence intervals for (a) the population variance o? and (b) the population standard deviation o. Interpret the results. (a) The confidence interval for the population variance is ( ). (Round to the nearest integer as needed.)
