**Need D & E only**

You may need to use the appropriate appendix table or technology to answer this question.

Recall the method used to obtain a confidence interval for the difference between two population means for matched samples.

(a)

The following data are from matched samples taken from two populations. Compute the difference value for each element. (Use Population 1 − Population 2.)

Element	Population	Difference
1	2
1	11	8
2	7	8
3	9	6
4	12	7
5	13	10
6	15	15
7	15	14

(b)

Compute

(c)

Compute the standard deviation

s_d.

(Round your answer to two decimal places.)

(d)

What is the point estimate of the difference between the two population means? (Use Population 1 − Population 2.)

(e)

Provide a 95% confidence interval for the difference between the two population means. (Use Population 1 − Population 2. Round your answers to two decimal places.)
