In a hypothesis test with hypotheses Ho : µ = 90 and H1 : u # 90, a random sample of 16 elements selected from the population produced a mean of 91.9 and a standard deviation of 4.9. The test is to be made at the 2% significance level. Assume the population is normally distributed. What is the p-value for this hypothesis test, rounded to four decimal places? Find the p-value for this hypothesis test, rounded to four decimal places, using any technology such as TI-84 calculator.
