Chapter 09, Testbank, Question 070-073 In a hypothesis test with hypotheses Ho : H < 54 and H1 : H > 54, a random sample of 24 elements selected from the population produced a mean of 59.1 and a standard deviation of 14.2. The test is to be made at the 2.5% significance level. Assume the population is normally distributed. What is the critical value of t? O 2.064 O 1.96 O -2.069 O 2,069 What is the value of the test statistic, t, rounded to three decimal places? What is the p-value for this hypothesis test, rounded to four decimal places? Should you reject or fail to reject the null hypothesis in this test? Reject. Fail to reject.
