Do consumers spend more on a trip to Store A or Store B? Suppose researchers interested in this question collected a systematic sample from 80 Store A customers and 78 Store B customers by asking customers for their purchase amount as they left the stores. The data collected is summarized by the accompanying table. Suppose researchers decide to test the hypothesis that the means are equal. The degrees of freedom formula gives 153.50 df. Test the null hypothesis at a 0.01. Identify the null and alternative hypotheses. Choose the correct answer below од Но на нано HA HA PO OB. Ho MAP 0 HAPA HD Q OC. Ho HAHe0 HA: PA-₂0 0.0.

Compute the test statistic. = (Round to two decimal places as needed.) Find the P-value. The P-value is (Round to three decimal places as needed.) State the conclusion. Choose the correct answer below. A. Reject the null hypothesis. There is sufficient evidence that the means are not equal. B. Fail to reject the null hypothesis. There is not sufficient evidence that the means are not equal. C. Reject the null hypothesis. There is not sufficient evidence that the means are not equal. D. Fail to reject the null hypothesis. There is sufficient evidence that the means are not equal.
