Please show your work

10. (10 points) Suppose that the NCAA requires that the standard deviation of softball circumferences not exceed 0.05 inches. 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 the standard deviation is 0.09 inches. Is there enough evidence to support the representative's belief at a significance level of 0.01? Assume that softball circumferences are normally distributed
