Childhood obesity: A national health survey weighed a sample of 537 boys aged 6-11 and found that 85 of them were overweight. They weighed a sample of 503 girls aged 6-11 and found that 72 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 1=0.01 level of significance and the critical value method with the table. a) State the appropriate null and alternate hypotheses. b) Compute the value of the test statistic. c) State a conclusion at the a =0.01 level of significance. Part 1 of 5 (a) State the null and alternate hypotheses. Ho: P1 = P2 H: P1 # P2 This hypothesis test is a two-tailed test. Part: 1 /5 Part 2 of 5 Find the critical value(s). Round the answer(s) to at least two decimal places. If there is more than one critical value, separate them with commas. Critical value(s):
