Question: In the hypothesis test example in this section, the critical value of \(t=1.717\) was obtained by using \(\mathrm{df}=\) smaller of \(n_{1}-1\) and \(n_{2}-1 .\) With sample sizes of 23 and 30, we used \(d f=22\). If we calculate df using Formula 9-1, we get \(df=41.868\), and the corresponding critical value is 1.682. How is using a critical value of \(t=1.717\) "more conservative" than using a critical value of 1.682?
