Pleаse nоte thаt this questiоn cоnsists of four pаrts. You need to show all mathematical calculations/explanations to get the final answer. Just giving the answer without showing work may result in zero for the question. The recommended tire pressure is 32 psi. The researchers want to know if drivers have tire pressure below the recommended value. They measure the tire pressure for 15 randomly selected cars and find that for this sample the average is 30.1 psi and the standard deviation 3 psi. Assuming tire pressure follows a normal distribution, answer below questions. State the null and alternative hypotheses to answer the researchers’ question. Calculate the test statistic for the test in part 1. You may use MINITAB to get the final test statistic. However, you need to show the mathematical calculation that resulted in the final answer. Calculate the p value for the test you formulated in part 1. Write the p value as a probability statement and then you may use Minitab to find the numerical value of the p value. Write the final conclusion in the context of the problem, use 5% significance level.
