Question 1149762: listed below are the systolic blood pressures if the same woman. simple random sample, distribution normal. .01 significance level to test difference between measurements. right 143,135,119,131,137. Left 182,161,179,139,136
Answer by Boreal(15235)   (Show Source):
You can put this solution on YOUR website! This is a paired t with df=4 and differences (L-R) of
39,26,60,8,-1
That mean is 132/5=26.4
sd is 24.38
critical value is t=4.604
test stat is mean/s/sqrt(n)
=26.4/24.38/sqrt(5)
=2.42
This has a p-value of 0.07
fail to reject Ho
arm systolic pressures with these data fail to show significant difference at the 0.01 level.
