A factory which produces steel ball bearings claims that the standard deviation in the weights of the bearings produced is 0.13 grams. A sample of 100 bearings is taken and the following result is obtained: s=0.15 grams Use a 0.02 significance level to test the claim that the bearings produced have a standard deviation of 0.13 grams. Employ both the traditional method and the p-value method.
