A car dealership is worried that Hondas are getting lower sales than Hyundai. Two independent random samples have been selected 630 observations from population 1 (Hondas) and 610 from population 2 (Hyundai). 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 Hondas are receiving lower sales? Fully explain your answer.
