Felix claimed that 15% of students drive Toyota Vios cars. Shang finds this hard to believe and wants to check the validity of Felix's claim. At a level of significance of 0.10, is there sufficient evidence to reject Felix's claim if there were 17 Toyota Vios in his sample of 200 cars? Many people sleep on the weekends to make up for "short nights" during the workweek. A recent study showed that 61% of us get more than seven hours of sleep per night on the weekend. A random sample of 350 adults found that 235 had more than seven hours of sleep each night last weekend. At 0.05 level of significance, does this evidence show that more than 61% sleep seven or more hours per night on the weekend? Which test of hypothesis is most appropriate for this study? Many students complained that the soft-drink vending machine A dispenses a different amount of drink than machine B. To test this belief, a student randomly sampled several servings from each machine and carefully measured them. Which test of hypothesis is most appropriate for this study? Choose... Choose..
