In order to test this belief, we randomly selected a sample of 36 of the company's gas stations and determined that the average price for the stations in the sample was $2.14. Assume that the standard deviation of the population (o) is $0.12. a. State the null and the alternative hypotheses b. Compute the test statistic. What is the p-value associated with the above sample results? d. Using a-,05, and.10 to test the company's claim and discuss your work
