The average gasoline price of one of the major oil companies has been hovering around $2.20 per gallon. because of cost reduction measures, it is announced that there will be a significant reduction in the average price over the next month. in order to test this belief, we wait one month, then randomly select a sample of 36 of the company's gas stations. we find that the average price for the stations in the sample was $2.15. the standard deviation of the prices for the selected gas stations is $.10. given that the test statistic for this sample is t = –3, determine the p-value.
