Webcritical value: The 97.5th percentile of the t-distribution with 29 degrees of freedom is 2.045; the rejection region is therefore any t-statistic greater than 2.045 or less than −2.045 (we need the 97.5th percentile in this case because this is a two-tail test, so we need half the significance level in each tail). WebA one-sided alternative is really H0 µ1 >= µ2 vs H1 µ1 < µ2. The side is below zero so you should use -2.447 for the critical value or if you want alpha =0.05 use -t0.950(6)=t0.05(6). …
