Question

Do consumers spend more on a trip to Store A or Store​ B? Suppose

researchers interested in this question collected a systematic sample from 85 Store A customers and 79 Store B customers by asking customers for their purchase amount as they left the stores. Suppose researchers decide to test the hypothesis that the means are equal. These results are summarized by the accompanying table. Repeat this​ test, but assume that the variances of the purchases amounts are the same at Store A and Store B. Did the conclusion​ change? Why do you think that​ is? Use α=0.10.


a) Compute the test statistic. T=___.
