You are interested in determining the amount of time you spend each day on the Internet. For a random seven days, you record the time (in minutes) that you spend on the Internet. These times are listed below.

         51       24      16     88     63    28    59    

Assuming that the amount of time you spend on the Internet each day is normally distributed, a 90% confidence interval for the mean time you spend each day on the Internet is:

Supose that the amount of the time teenagers spend weekly working at part-time job is normally distributed with a standard deviation of 40 minutes. A random sample of 15 teenagers was drawn, and each reported the amount of time spent at part-time jobs (in minutes). These are listed here. Determine the 95% confidence interval estimate of the population mean. 180, 130, 150, 165, 90, i130, 120, 60, 200, 180, 80, 240, 210, 150, 125

You own a small storefront retail business and are interested in determining the average amount of money a typical customer spends per visit to your store. You take a random sample over the course of a month for 45 customers and find that the average dollar amount spent per transaction per customer is $90.422 with a standard deviation of $13.895.

Executives of a supermarket chain are interested in the amount of time that customers spend in the stores during shopping trips. The executives hire a statistical consultant and ask her to determine the mean shopping time, μ, of customers at the supermarkets. The consultant will collect a random sample of shopping times at the supermarkets and use the mean of these shopping times to estimate μ. Assuming that the standard deviation of the population of shopping times at the supermarkets...
