The manager of a paint supply store wants to determine whether the mean amount of paint contained in 1-gallon cans purchased from a nationally known manufacturer is actually 1 gallon. You know from the manufacturer's specifications that the standard deviation of the amount of paint in a 1-gallon can is 0.02 gallons. You select a random sample of 50 cans, and the mean amount of paint per 1-gallon can is 0.995 gallons.

a. Is there evidence that the mean amount is different from 1.0 gallons?

b. Compute the p-value for your test
