- A radio station states that 30% of the songs they play each week are from Canadian artists. A DJ working at the station claims that the actual percentage differs from what the station states. The DJ takes a random sample of 87 songs played during a given week and finds that 28 of them are from Canadian artists. Use this information to answer the questions below. a. Suppose the DJ wishes to perform a hypothesis test of his claim. Select the most appropriate null and alternative hypotheses for this hypothesis test.

She read a magazine article that stated that 9 out of 10 college students, or 90%, prefer face-to-face lecture courses rather than online classes. Lynell thought that this number seemed high. It seemed to her that more than 10% of students prefer online lecture classes because online classes allow for more flexible schedules. To test this claim, Lynell formulated the following null and alternative hypotheses. Ho: p = 0.90 H₁: p < 0.90 The variable p represents the proportion of all students who prefer face-to-face lecture courses to online courses. The alternative hypothesis, H₁, represents her claim that fewer than 90% of students prefer face-to-face classes. Next, she randomly surveyed 275 students at her college, which she took to be a simple random sample of all students attending large state colleges like hers. Her survey results are displayed below.

- According to the Centers of Disease Control, about 9% of Americans between the ages of 12 and 19 have asthma. A student claims that the students in his school differs from the national average, so their proportion of students with asthma is not 9%. Which are the appropriate null and alternative hypotheses for this study? Ho: p = 0.09 Ha: p 0.09 Suppose that the result of the statistical test is to reject Ho. Which is the proper conclusion? O The test has proved that the students at his school have a different proportion of students with asthma. O There is sufficient evidence to support the claim that the students at his school have a different proportion of students with asthma. O There is not enough information to answer this question.
