Learn By Doing, Example 2 In this activity we will use example 2. Recall that we've just completed this example, and summarized it using the following figure: Sample (lOOstudents) Students at the college Conditions Use marijuana p e '" m\" Ho=p=-157 B=19noo=.19 H.:p>.157 4, Jr iv p-value = .182 Conclusion: H. cannot be rejected. We've seen that the evidence the data provided19 marijuana users out of a sample of loowas not enough for us to conclude that the proportion of marijuana users in the college is higher than the national gure (0.157). An interesting question, therefore is: How many marijuana users out of 100 should we have found for it to be enough evidence to reject Ho ? 19 was not enough, but what woutd have been enough? 21? 25? ? Learn By Doing A What do you think is the minimum number of marijuana users (out of 100 students) that would constitute enough evidence to reject Ho and conclude that is greater than 0.157? Use just your intuition. If you needed to decide whether to reject H0 or not based on a sample of size 100 students, how many marijuana users would you need to nd to convince you that indeed. p Is greater than 0.157?
