In a hypothesis test with the null and alternative hypotheses hypotheses Ho : µ > 80 and H1 : µ < 80, a random sample of 99 elements selected from the population produced a mean of 75.3. Assume that o = 24.6, and that the test is to be made at the 5% significance level. What is the p-value for this hypothesis test, rounded to four decimal places?
