Childhood obesity: A national health survey weighed a sample of 532 boys aged 6-11 and found that 89 of them were overweight. They weighed a sample of 469 girls aged 6-11 and found that 71 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 p₁ denote the proportion of boys who are overweight and let p₂ denote the proportion of girls who are overweight. Use the a = 0.10 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= 0.10 level of significance. Part 1 of 5 (a) State the null and alternate hypotheses. Ho: P₁ = P₂ H₁: 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): 0.0....
