6. Research by Harvard Medical School experts suggests that boys are more likely than girls to grow out of childhood asthma when they hit their teenage years. Scientists followed over 1,000 children between the ages of 5 and 12, all of whom had mild to moderate asthma. By the age of 18, 14% of the girls and 27% of the boys seemed to have grown out of asthma. Suppose their analysis was based 500 girls and 500 boys. on At a 0.01, test whether the proportion of boys growing out of childhood asthma is at least 6% more than the proportion of girls. Use the p-value approach. In particular, address the following questions. (a) What is the claim as an equation or inequality? (b) What are the null hypothesis and alternative hypothesis as equations or inequalities? (c) Is this test left-tailed, right-tailed, or two-tailed? (d) Calculate the test statistic z to determine the p-value and compare it to a. (e) What is the conclusion?
