Chapter B.3, Problem 18AYU

NCAA Softball NCAA rules require the circumference of a softball to be 12 ± 0.125 inches. Suppose that the NCAA also requires that the standard deviation of the softball circumferences not exceed 0.05 inch. A representative from the NCAA believes the manufacturer does not meet this requirement. She collects a random sample of 20 softballs from the production line and finds that s = 0.09 inch. Is there enough evidence to support the representative’s belief at the α = 0.05 level of significance?
