Given two dependent random samples with the following
results:
Can it be concluded, from this data, that there is a significant
difference between the two population means?
Let d=(Population 1 entry)−(Population 2 entry).
Use a significance level of α=0.02 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 H0H0. Round the numerical portion of your answer to
three decimal places.
Step 5 of 5:
Make the decision for the hypothesis test.
