Consider the confidence interval estimate discussed in Problem 1. Suppose the population mean time spent on the site is 36 minutes a day. Is the confidence interval estimate stated in Problem 1 correct? Explain.
In Problem 1
A market researcher selects a simple random sample of n = 100 Twitter users from a population of over 100 million Twitter registered users. After analyzing the sample, she states that she has 95% confidence that the mean time spent on the site per day is between 15 and 57 minutes. Explain the meaning of this statement.
