Do consumers spend more on a trip to Target or Walmart? Suppose researchers interested in this question collected a systematic sample from 83 Target customers and 82 Walmart customers by asking customers for their purchase amount as they left the stores. The data collected formula gives 159.83 df. Test the null hypothesis at a= 0.01. Target Walmart summarized by the accompanying table. Suppose researchers decide to test the hypothesis that the means are equal. The degrees of freedom 83 82 y 43 52 21 18 Identify the null and alternative hypotheses. Select the correct choice below.
