A.Assume that the crime rate distribution is approximately normal in both regions. Do the data indicate that the violent crime rate in the Rocky Mountain region is higher than in New England? Use = 0.01. Solve the problem using both the traditional method and the P-value method. (Test the difference _{1 2}. Round the test statistic and critical value to three decimal places.)
