Question

Assume that you want to test the claim that the paired sample data come from a population for which the mean difference is muμSubscript ddequals=0. Compute the value of the t test statistic. Round intermediate calculations to four decimal places as needed and the final answer to three decimal places as needed.

x:37 32 19 25 30 24 32 35

y: 35 28 25 25 31 29 32 34

Answer 1

x	y	Difference(d)
37	35	2
32	28	4
19	25	-6
25	25	0
30	31	-1
24	29	-5
32	32	0
35	34	1
	Total	-5

Sample size = n = 8

Sample mean of difference = = - 0.625

Sample standard deviation of difference = = 3.3780

Test statistic is

The value of the t test statistic = - 0.523
