Chapter 09, Testbank, Question 074-077 In a hypothesis test with hypotheses Ho : H = 90 and H : H # 90, a random sample of 16 elements selected from the population produced a mean of 85.9 and a standard deviation of 6.6. The test is to be made at the 10% significance level. Assume the population is normally distributed. What are the critical values of t? O -1.645 and 1.645 -1.753 and 1.753 -1.341 and 1.341 -1.746 and 1.746 What is the value of the test statistic, 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 reject.
