Question

The following table contains information on matched sample values whose differences are normally distributed. (You may find it useful to reference the appropriate table: z table or t table)

Number	Sample 1	Sample 2
1	16	20
2	12	13
3	20	22
4	20	22
5	17	20
6	14	16
7	16	18
8	18	21

a. Construct the 99% confidence interval for the mean difference μ_D. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places and final answers to 2 decimal places.)
