On hundred and fifty-one (151) De Anza College students were surveyed and asked two questions: (1) How many units are you taking this quarter, and (2) How many hours of television do you watch per day. The chart below summarizes the data. We wish to conduct a hypothesis test to determine if the number of units a student takes is independent of the number of hours per day of television the student watches. Number of units Hours of T.V. per day à 5.1 or 0-1 1.1 - 3 3.1 - 5 Totals more 0 - 5 4 12 13 10 39 5.25 - 10 3 11 27 10.25 - 15 18 16 10 48 15.25 or 11 14 7 37 more Totals 36 53 39 23 151 At the 1% level, the correct decision is: O Do not reject the null hypothesis. Reject the null hypothesis. O The test is inconclusive. O There is not enough information to make a decision.
