Step 1

In this case, α=0.02,n₁=15 and n₂=8.

It is also known that the population variances are equal.

$\begin{array}{rcl} D f & = & n_{1} + n_{2} - 2 \\ = & 15 + 8 - 2 \\ = & 23 - 2 \\ = & 21 \end{array}$

Here, the alternative is two-tailed.

Using excel function, “=T.INV.2T(0.02,21)”, the critical value for two-tailed test is ±2.518.
