Given two dependent random samples with the following results:
Population 1 52 81 72 67 73 73 76 83
Population 2 61 71 82 62 79 77 71 85
Can it be concluded, from this data, that there is a significant difference between the two population means? Let d = d (Population 1 entry) − (Population 2 entry). Use a significance level of α = 0.01 for the test. Assume that both populations are normally distributed.
Step 1 of 5: State the null and alternative hypotheses for the test.
Step 2 of 5: Find the value of the standard deviation of the paired differences. Round your answer to one decimal place.
Step 3 of 5: Compute the value of the test statistic. Round your answer to three decimal places.
Step 4 of 5: Determine the decision rule for rejecting the null hypothesis H0. Round the numerical portion of your answer to three decimal places.
Step 5 of 5: Make the decision for the hypothesis test. Reject or Fail to regect Null Hypotthesis.
