A sporting goods store believes the average age of its customers is 37 or less. A random sample of 41 customers was surveyed, and the average customer age was found to be 39.5 years. Assume the standard deviation for customer age is 8.0 years. Using α=0.10, complete parts a and b below. Does the sample provide enough evidence to refute the age claim made by the sporting goods store? Determine the null and alternative hypotheses. H0 : H1 : Test statistics = Critical Value = P value =
