Question 1104885
Ho: same
Ha: unequal
test statistic is t df=93
critical value is |t|> 1.97
t=(xbar1-xbar2)/sqrt ((s1^2/n1)+s2^2/n2)); sqrt term is 0.462+0.277=0.739; sqrt (0.739)=0.860
t=1.95/0.86=2.27, which is greater than 1.97 test statistic.
Can conclude there is a difference at the 0.05 level.
