The manager of a cell phone store in the Valley Mall recently collected data on a sample of 50 customers who purchased a cell phone and a monthly call plan.

The data she recorded are in the data file called Phone Survey.

a. The manager is interested in describing the difference between male and female customers with respect to the price of the phone purchased. She wants to compute the mean and standard deviation of the phone purchase price for each group of customers.

b. The manager is also interested in an analysis of the phone purchase price based on whether the use will be for home or business. Again, she wants to compute the mean and standard deviation of the phone purchase price for each group of customers.
