The data to the right show the average retirement ages for a random sample of workers in Country A and a random sample of workers in Country B. Complete parts a and b. Sample mean Sample size Population standard deviation Country A 63.9 years Country B 65.5 years 30 30 4.2 years 4.8 years a. Perform a hypothesis test using a = 0.05 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. OA. Ho H1 H2<0 H₁: 1220 OC.
