Question for mathematical genius! (Please help)For the current inquiry, they are interested in whether teens who smoke have a lower FEV on average than teens who do not smoke. They included subjects aged 13-15 only.Treat the data as a random sample and perform a total of four hypothesis tests (are able to use Excel) One for the overall group of teenage subjects, and one for each age group:13-year-olds, 14-year-olds, and 15-year-olds. For each test, use the mean FEV of nonsmokers in the associated group as the null hypothesis. Do the datasuggest that the mean FEV of smokers is less than the mean FEV of nonsmokers? Perform all tests at a significance level of a = 0.05.For each hypothesis test include the following:? State null and alternative hypotheses clearly regarding the well-defined parameter of interest.? Provide summary statistics such as sample mean and sample standard deviation.
