Basic Math

Given two dependent random samples with the followingresults:

Population 1 32 35 45 46 43 45 30

Population 2 19 40 31 32 30 47 42

Use this data to find the 90% confidence interval for the truedifference between the population means. Assume that bothpopulations are normally distributed.

Step 1 of 4: Find the point estimate for the population mean ofthe paired differences. Let x1 be the value from Population 1 andx2 be the value from Population 2 and use the formula d=x2?x1 tocalculate the paired differences. Round your answer to one decimalplace.

Step 2 of 4: Calculate the sample standard deviation of thepaired differences. Round your answer to six decimal places.

Step 3 of 4: Calculate the margin of error to be used inconstructing the confidence interval. Round your answer to sixdecimal places.

Step 4 of 4: Construct the 98% confidence interval. Round youranswers to one decimal place.
