Question
Given two independent samples with means = 33 and 24, the estimated standard error = 3, and each sample had 5 scores, what is the p-value for: a two-tailed test? a one-tailed test?
two-tailed: p < .01 ; one-tailed: p < .001
two-tailed: p < .01 ; one-tailed: p < .01
two-tailed: p > .05 ; one-tailed: p < .05
two-tailed: p < .05 ; one-tailed: p < .05
two-tailed: p < .05 ; one-tailed: p < .01
a.two-tailed: p < .01 ; one-tailed: p < .001
b.two-tailed: p < .01 ; one-tailed: p < .01
c.two-tailed: p > .05 ; one-tailed: p < .05
d.two-tailed: p < .05 ; one-tailed: p < .05
e.two-tailed: p < .05 ; one-tailed: p < .01
Explanation / Answer
Ans:
degree of freedom=5+5-2=8
t =(33-24)/3=9/3=3
Two tailed test:
p-value(2 tailed)=0.0171
One tailed test:
p-value(right taile)=0.0085
two tailed:p<0.05;one tailed:p<0.01
Option e is correct.
