11) A national health survey weighed a sample of 531 boys aged 6-11 and found that 86 of them were overweight. They weighed a sample of 544 girls aged 6-11 and found that 65 of them were overweight. Can you conclude that the proportion of boys who are overweight differs from the proportion of girls who are overweight? Use the 0.05 level of significance and the P-value method. (a) State the appropriate null and alternate hypotheses. (b) Compute the P-value. (c) Determine whether to reject Null Hypothesis. d) State a conclusion.
