A sporting goods store believes the average age of its customers is 34 or less, but a competitor wants to challenge this. A random sample of 38 customers was surveyed, and the average customer age was found to be 37.5 years. Assume the standard deviation for customer age is 7.0 years. Using a = 0.05, complete parts a through d below a. Does the sample provide enough evidence to refute the age claim made by the sporting goods store? Determine...
