Accepts Credit Cards Does not Accept Credit Cards Public 4 - year 84 16 Private 4 - year 78 35 Community College 103 7 Use this information to complete test for independence at a 0.05 level of significance. 1. What are the null and alternative hypotheses for the test for independence in this situation. Ho: [null] H1: [alt] 2. Find the test-statistic and the p-value for the hypothesis test.

In the table of expected values, what is the entry for the cell corresponding to Community College and Accepts Cards? [ans4] 5. Why did this data set meet the criteria for completing the hypothesis test? All [obs] frequencies are greater than or equal to [five].
