Studdy Solution
Compare the test statistic to the critical values:
Since $-2.064 < -0.963 < 2.064$, we fail to reject the null hypothesis $H_0: \mu_1 = \mu_2$.
The conclusion is that there is not enough evidence to reject the claim that the population means are equal at the 0.05 significance level.
