Given two dependent random samples with the following results: Population 1 30 15 28 44 26 47 32 Population 2 44 28 36 35 18 35 22 Use this data to find the 95% confidence interval for the true difference between the population means. Assume that both populations are normally distributed. Step 1 of 4 :Find the point estimate for the population mean of the paired differences. Let x1 be the value from Population 1 and x2 be the value from Population 2 and use the formula d=x2−x1 to calculate the paired differences. Round your answer to one decimal place.

Given two dependent random samples with the following results:
Population 1 | 30 | 15 | 28 | 44 | 26 | 47 | 32 |
---|---|---|---|---|---|---|---|
Population 2 | 44 | 28 | 36 | 35 | 18 | 35 | 22 |
Use this data to find the 95% confidence interval for the true difference between the population means. Assume that both populations are
Step 1 of 4 :Find the point estimate for the population mean of the paired differences. Let x1 be the value from Population 1 and x2 be the value from Population 2 and use the formula d=x2−x1 to calculate the paired differences. Round your answer to one decimal place.
