Childhood obesity: A national health survey weighed a sample of 538 boys aged 6-11 and found that 89 of them were overweight. They weighed a sample of 522 girls aged 6-11 and found that 61 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight? Let p, denote the proportion of boys who are overweight and let p, denote the proportion of girls who are overweight. Use the a = 0.05 level of significance and the P-value method with the TI-84 Plus calculator. Part 1 of 4 State the appropriate null and alternate hypotheses. HO: P1 = P2 H1: P1 * P2 This is a two-tailed test. Part 2 of 4 Find the P-value. Round the answer to four decimal places. P-value = 1 Part 3 of 4 Determine whether to reject Ho. Reject the null hypothesis Ho- Part: 3 / 4 Part 4 of 4 State a conclusion. There is enough evidence to conclude that the proportion of boys who are X overweight differs from the proportion of girls who are overweight. 5
