Question
A market researcher collects a simple random sample of customers from its population of over a million customers After analyzing the sample, she states that she has 95% confidence that the mean time spent on the site per day is between 20 and 51 minutes Suppose that the population mean time spent on the site is 26 minutes a day Is the confidence interval estimate correct? Explain Choose the correct answer below No. because the value of p is not the midpoint of the confidence interval estimate Yes. because the value of p is included within the confidence interval estimate No. because the value of p is not included within the confidence interval estimate Yes. because the value of p is within 95% of the midpoint of the confidence interval estimate No. because the value of p is not in the middle half of the confidence interval estimateExplanation / Answer
95% Confidence interval for Population mean is (20,51)
Population mean is 26 min
Hence popualtion mean(Mu) is included within the confidence interval estimeate
