Questions 11-12: Most experts recommend college students get at least 8 hours of sleep per night. You collect a random sample of 112 students at your college and ask how many hours of sleep they got last night. The sample mean amount of sleep last night was 7.6 hours, with a sample standard deviation of 2.1 hours. You want to know: Does this provide evidence that students at your college are getting less than the recommended amount of sleep per night? To answer this question, you construct a null hypothesis and do a hypothesis test using an applet: 11. What is the null hypothesis? State the null hypothesis. Null hypothesis: a 12. Do these results provide evidence that students at your college are getting less than the recommended amount of sleep per night? Use the Theory-Based Inference applet to answer this question. Explain
