Question

A grocery store purchases fresh fish every day from its supplier. It has ordered 100 pounds of fish each day, but the weight actually received varies from day to day with an average range of 6 pounds. Over the past five days it received the following weights of fish: 106, 94, 102, 100, and 97 pounds.
a. Using this five-day sample, is the process of the fish supplier in control in average and range?
b. How can the supplier more carefully control the process to provide nearly 100 pounds of fish each day?
