Test the hypothesis that of > 62 at the a = 0.05 level Population 1 Population 2 of significance for the given sample data. Assume that the populations are normally distributed. Use C O the P-value approach. 12.8 State the null and alternative hypotheses, for this test. Ho: VI Ha: Use tech d the P-value for this test. The P-va Round t nal places as needed.) Make a s garding the null hypothesis and draw a conclusion for this test. F Since the r-value to the a = 0.05 level of significance, the null hypothesis. There sufficient evidence to conclude that the standard deviation of Population 1 is significantly greater than the standard deviation of Population 2 at the a = 0.05 level of significance
