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. Ho H₁₂≤0 H₁: H1-H20 O E. Ho H1 H2=0 H₁: H1-420 OB. Ho: H1 H2>0 H₁: H1 H2 ≤0 OD. Ho: H1 H2 20 H₁₁-20 OF. Ho: H1 H2 #0 H₁: H1 H2 =0
