The sample means obtained are X1(bar)=$46 k and X2(bar)=$47 k. It is known from previous studies that the population variances are 4.1 and 5.0 respectively. Using a level of significance of .05, is there evidence that the first year female high school teachers are receiving lower salaries? Fully explain your answer.
