Question
What value cuts off 0.025 in the upper tail of the t distribution on 18 df 1.734 2.101 2.110 2.093 2.552 You do hypothesis test of H_0: mu = 5 vs H_a: mu not equal to 5 at significance level 0.05. You collect a random sample and find your test statistic z = 2.10 What is the p value equal to 5 0.4821 0.0179 0.05 0.0358 can't be determined You know that the distribution of test scores is normal with a historic mean of 100. You think that a new study program has increased the mean and wish to test the claims H_0: mu = 100 vs H_s: mu > 100. You collect a random sample of 16 tests and find in this sample a mean of 110 and standard deviation of 20. What is the appropriate test statistic t = 2.00 on 16 df t = 1.94 on 16 df z = 2.00 on 16 df t = 2.00 on 15 df t = 1.94 on 15 df z = 2.00 on 15 df You conduct a test of H_0: mu = 20 vs H_a: mu not equal to 20 and get a test statistic t = 2.764 on 10 df. What is the p value 0.01 0.02 0.025 0.05 0.10 cannot be determinedExplanation / Answer
