Expert Solution
Step 1
Obtain the 95% confidence interval for the mean difference between the before and after scores.
The 95% confidence interval for the mean difference between the before and after scores is obtained below:
The formula for the Confidence interval for paired differences between the mean is:
Obtain the degrees of degrees of freedom.
The degrees of freedom are obtained below:
From the information, given that there is a sample of 10 participants.
Thus, the degrees of freedom used are 9.
