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 $3370. Assume the sample is taken from a normally distributed population. Construct 99% confidence intervals for (a) the population variance o² 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.) 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.) O A. With 1% confidence, you can say that the population variance is between O B. With 1% confidence, you can say that the population variance is greater than and. O C. With 99% confidence, you can say that the population variance is less than O D.
