Use tables in the Appendix to specify the appropriate Rejection Region ONLY for each hypothesis test described below

a) H0: σ12 / σ22 = 1 (With sample sizes n1 = 25 and n2 = 16.) Ha: σ12 / σ22 < 1 α = .05

b) H0: There is no significant difference in Block Means. Ha: There is a significant difference in at least some pair(s) of Block Means. α = .01 (With 6 Treatments and 25 Blocks.)

Conduct each hypothesis test below using both the critical value/rejection region and p-value methods (separate and label each method) and showing each of the 5 steps explicitly. Do not round any table values. Round test statistics to the nearest hundredth, critical values to 3 decimal places, and p-values to 4 decimal values. Many computer buyers have discovered that they can save a considerable amount by purchasing a personal computer from a mail-order company - an average of $900 by their...

For all hypothesis tests, use both the critical value/rejection region and p-value (separate and label each method) and show each of the 5 steps explicitly. A. The internal revenue service believes that the number of business executives who default on their tasks is larger than the proportion of 'blue collar' workers. Out of 150 business executives, 24 default on their taxes. For a sample of 75 'blue collar' workers has only 8 that default on their taxes. Test the hypothesis...

Match the scenario with the appropriate hypothesis test. Each word test may only be used once. Zach has just started running for the first time. He would like to track his mileage with a fitness app on his phone. He finds two apps; one that is free and one that costs money. He doesn’t want to pay money if the apps are equally as good at tracking his mileage. He decides to test the two apps. He chooses 10 routes...

A) A test statistic value of 2.14 puts it in the rejection region. If the test statistic is actually 2.19 then we know the p-value is less than the significance level for the test. True or false? Explain. B) The null hypotheses is false. The p-value is less than the significance level. Do we have a type 1 error, a Type 2 error, or a correct decision. Give an explanation. C) For a right tailed test a test statistic of...
