A two-sample z-test for two population proportions is to be performed using the P-value approach. The null hypothesis is H_0: P_1=P_2 and the alternative is H_a: P_1≠ P_2. Use the given sample data to find the P-value for the hypothesis test. Give an interpretation of the p-value. A poll reported that 30% of 60 Canadians between the ages of 25 and 29 had started saving money for retirement. Of the 40 Canadians surveyed between the ages of 21 and 24, 25% had started saving for retirement.
