The following data are from matched samples taken from two populations. Population Element 1 2 1 9 6 2 11 15 3 15 12 4 11 12 5 9 13 6 14 6 7 10 11 a. Compute the difference value for each element (difference between element of population 1 and population 2 and enter negative values as negative numbers, if any). If your answer is zero, enter "0". Element Difference Value 1 2 3 4 5 6 7 b. Compute d (to 3 decimals). Enter negative value as negative number, if any. c. Compute the standard deviation sd (to 3 decimals). d. What is the point estimate of the difference between the two population means (to 3 decimals)? Enter negative value as negative number, if any. e. Provide a 95% confidence interval for the difference between the two population means (to 3 decimals and enter negative values as negative numbers, if any).

b. Compute d (to 3 decimals). Enter negative value as negative number, if any.
c. Compute the standard deviation sd (to 3 decimals).
d. What is the point estimate of the difference between the two population means (to 3 decimals)? Enter negative value as negative number, if any.
e. Provide a 95% confidence interval for the difference between the two population means (to 3 decimals and enter negative values as negative numbers, if any).
