Question
Looking at the table below what do you conclude in a test of weekly expenditure on fruit between females and non-females if one were testing the null hypothesis of no difference against a 1-sided
alternative that females spend more on fruit at the 5% significance level:
Two-sample t test with equal variances
Group Obs Mean Std. err. Std. dev. [95% conf. interval]
Female 377 14.661 .4317 8.381 13.812 15.510
Non-Female 206 13.801 .5113 7.339 12.793 14.809
Combined 583 14.357 .6956 8.033 13.703 15.011
diff
.8602 .6957
-.5061 2.2265
diff= mean(Female) - mean(Non-Female)
HO: diff = 0
Ha: diff < 0
Pr(Tt) = 0.892
Ha: diff != 0
Pr(|T| > |t|) = 0.217
With a p-value of 0.892 we do not reject HO
With a p-value of 0.892 we accept HO
With a p-value of 0.108 we do not reject HO
With a p-value of 0.217 we do not reject HO
t = 1.237
Degrees of freedom = 581
Ha: diff > 0
Pr(T>t) = 0.108
