It has been claimed that for the population of U.S. commercial jets, the mean age is less than 18 years. To test this claim, a random sample is selected from the population. The sample statistics include n=37, x = 15.8 years and s=8.3 years. Do the sample data provide sufficient evidence to conclude that the population mean age is less than 18 years? Conduct hypothesis test using a=.01. Use the traditional approach and the p-value approach to hypothesis testing! Show all of the steps of the hypothesis test for each approach
