Question

Given two dependent random samples with the following results:

Population 1	34	34	34	20	27	18	41
Population 2	48	25	40	18	24	23	27

Use this data to find the 90% confidence interval for the true difference between the population means.

Let d=(Population 1 entry)−(Population 2 entry)d=(Population 1 entry)−(Population 2 entry). Assume that both populations are normally distributed.

Step 2 of 4: Find the critical value that should be used in constructing the confidence interval. Round your answer to three decimal places.

Step 3 of 4: Find the standard deviation of the paired differences to be used in constructing the confidence interval. Round your answer to one decimal place.

Step 4 of 4: Construct the 90% confidence interval. Round your answers to three decimal places.
