Country A Counuy B 67.2 years 40 655 years Sample mean Sample size Population 40 standard deviation 4.3 years 5.4 years a. Perform a hypothesis test using a = 0.01 to determine if the average retirement age in Country B is higher than it is in Country A. Let population 1 be the workers in Country A and population 2 be the workers in Country B. Identify the null and alternative hypotheses. Choose the correct answer below. O A. Ho -2 #0 H, -2 =0 OC.
