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 thatshe has 95% confidence that the mean time customers spent on that website per day is between 17 and 55 minutes. Suppose that the population mean time customers spent on that website is 16minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.Chood the correct answer below.OA. Yes, because the population mean, u, is relatively close to the confidence interval estimate.OB. Yes, because the population mean, u, is included within the confidence interval estimate.OC. No, because the population mean, u, is not included within the confidence interval estimate.OD. No, because the population mean, u, is not the midpoint of the confidence interval estimate.OE. Yes, because the population mean, uis within 95% of the midpoint of the confidence interval estimate.F3F4$F5%5F66F7DELLF8&77F9★88F10(F11OF12Activate WindowsGo to Settings to activate WindowsNextgPrtScr4Insert9:09 AM12/19/2022DeleteBackspace

A researcher from a national reading program conducted a poll of 650 American adults over the age of 30-years-old and asked how many books they read over the past year. The researcher reported that American adults over the age of 30-years-old read a mean number of 13.5 books. The report included a margin of error of 1.25 books. (Assume 95% confidence was used.)
