<PRE><B>Question 1194199</B>
This is a paired t-test with df=4
critical value with alpha=0.1 is t=2.132
Ho: difference =0
Ha: difference NE 0
alpha=0.1 p{reject Ho|Ho true}=0.1
test is t=(x bar)*s/sqrt(n)
x bar is 5 and s 1.58
t=5/1.58/sqrt(5)=7.08
Can conclude that there is a significant difference from 0.
p-value=0.002
