Finding the Standard Deviation of Sample Mean Differences
In the last task, you computed the difference of the two sample means. To determine whether this difference is significant, you need to find the standard deviation of the sample mean differences. For this activity, you'll use the formula for the standard deviation of sample mean differences:
In this formula, the subscripts and represent the means of the two samples, and are the standard deviations of the two populations, and and are the two sample sizes.
Part A
What is the sample size of each population?
Part B
Use the standard deviation values of the two samples and find the standard deviation of the sample mean differences. Round your answer to two places.
