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 54 minutes. Suppose that the population mean time customers spent on that website is 14 minutes a day. Does this value of the population mean help to show that the confidence interval estimate is correct? Explain.

Part 1
Choose the correct answer below.
No, because the population mean,
μ,
is not the midpoint of the confidence interval estimate.Yes, because the population mean,
μ
is within 95% of the midpoint of the confidence interval estimate.No,
because the population mean,
μ,
is not
included within the confidence interval estimate.Yes, because the population mean, μ, is relatively close to
the confidence interval estimate.Yes,
because the population mean,
μ,
is
included within the confidence interval estimate.Expert Solution
