The Statistics Games are played by a large number of students across the county. Last year, 32% of Clayton State participated in the Games. You wonder: “Has the proportion increased this year?”. To find out, you take a random sample of 250 CSU students and ask them if they participated in the Games this year. You find that 38% did. Do you reject or fail to reject the null, using a significance level of 5%? What does that mean, in context of the problem? A We reject the null. There is strong evidence that the proportion of CSU students who participated in this year's Games has increased from 32%. B We fail to reject the null. There is evidence that the percent of CSU students who participate is 38%. C We fail to reject the null. There is strong evidence that the proportion of CSU students who participated in this year's Games has increased from 32%. D We fail to reject the null. There is not enough evidence to say that the proportion of CSU students who participated in this year's Games has increased. E We reject the null. There is evidence that the percent of CSU students who participate is 38%.
