You would like to conduct a hypothesis test to see if there is a difference between a Jackson Hewitt (JH) and H&R Block (HR) tax returns.We have randomly selected 15 tax returns and will have both JH and HR prepare them and see if there is a difference.Use the following information:

A.What is the test statistics value (correct number of decimal places depending on which test statistic)?

B.What is the probability of the test statistic for this specific problem? (take into consideration if this is 1-tail or 2-tail test)

C.What conclusion will you come to? (just need to state Accept Ho or Reject Ho and Accept Ha - just put one of those 2 answers in the body of the discussion board, but you will have a more detailed solution (besides writing one of these statements you will write out in words what the conclusion means) on your worksheet that you will attach as a PDF).Use a level of significance of .05.

D.Using the critical value approach at what critical value or values will you start rejecting the null hypothesis? (make sure you are very careful and detailed with your answer, pay attention to signs and values)
