Question

Using the table below. Answer the following questions: 9.08 8.804:17 267 3.66 6.843.731.63 9.54 3.04

Answer 1

Ans:

	A	B
1	9.08	6.84
2	8.8	3.73
3	4.17	1.63
4	2.67	9.54
5	3.66	3.04
mean=	5.676	4.956
std. dev.=	3.030	3.194

22)df=5+5-2=8

23)pooled standard deviation=sqrt((4*3.03^2+4*3.194^2)/8)=3.11

24)standard error for difference=3.11*sqrt((1/5)+(1/5))=1.969

Test statistic:

t=(5.676-4.956)/1.969

t=0.366
