Professor Nord stated that the mean score on the final exam from all the years he has been teaching is a 79%. Colby was in his most recent class, and his class’s mean score on the final exam was 82%. Colby decided to run a hypothesis test to determine if the mean score of his class was significantly greater than the mean score of the population. α = .01. What is the mean score of the population? What is the mean score of the sample? Is this test one-tailed or two-tailed? Why?
The test statistic in a right-tailed test is z=−1.83. Determine the P-value and decide whether, at the 5% significance level, the data provide sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis. The P-value is _____________ (Round to three decimal places as needed.) This P-value _____________________ (does not provide or provides) sufficient evidence to reject the null hypothesis in favor of the alternative hypothesis because it is_____________ (greater than or less than) the significance level.
You are conducting a hypothesis test on the body weights of male fraternity members. The research (alternative) hypothesis is that the averge weight is less than 200 lbs. Your test will be at the 0.01 significance level. You take a sample of 100 men, and find that the sample average is 210 lbs, and the standard error is 2 lbs. What is the value of your test statistic? (Please answer to two decimal places. ex: 5.43)
