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 17 and 51 minutes. Suppose that the population mean time customers spent on that website is 19 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.

Transcribed Image Text: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 17 and 51 minutes. Suppose that the population mean time customers spent
on that website is 19 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.
Choose the correct answer below.
O A. No, because the population mean, μ, is not the midpoint of the confidence interval estimate.
O B. Yes, because the population mean, µ is within 95% of the midpoint of the confidence interval estimate.
O C. No, because the population mean, μ, is not in the middle half of the confidence interval estimate.
O D. No, because the population mean, µ, is not included within the confidence interval estimate.
OE. Yes, because the population mean, μ, is included within the confidence interval estimate.
