Question Viewer (Round to two decimal places U [Q][Q needed.) Choose the correct answer below. Q Search A market researcher collects a simple random sample of customers from a population of over a million customers that use a home improvement website. After analyzing the sample, she states that she has 95% confidence that the mean time customers spent on that website per day is between 19 and 52 minutes. Suppose that the population mean time customers spent on that website is 47 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain. Screen Shot 2022-07-09 at 1.19.49 PM OA. Yes, because the population mean, u is within 95% of the midpoint the confidence interval estimate. OB. Yes, because the population mean, µ, is included within the confidence interval estimate. O C. No, because the population mean, u, is not the midpoint of the confidence interval estimate. O D. No, because the population mean, μ, is not included within the confidence interval estimate. O E. No, because the population mean, μ, is not in the middle half of the confidence interval estimate. If x=88, S=21, and n=16, and assuming that the population is normally distributed, construct a 99% confidence interval estimate of the population mean, µ.
