The National Gymnastics Association wants to determine whether the weights of their registered gymnasts are in-line with international safety requirements. On average a gymnast should weigh about 140 bs with a population standard deviation of 15 ibs. To determine whether the variability has changed, a sample of 32 gymnasts were weighed and found to have a standard deviation of 14bb. Conduct the necessary hypothesis test to determine if there has been a change in the variability of the gymnasts' weight, assuming the p-value for this test is 0.531 and the population from which thus sample was taken is normally distributed. Based on the information above, what is the test statistic? Select one: a. 14.0 b. 270 C. 15.0 d. 28.9
