in a survey, 15 high school students said they could drive and 15 said they could not. Out of 60 college students surveyed, 30 s
aid they could drive.Micah concluded that if someone is in college, that mean the person is more likely to drive. Is Micah's conclusion correct? Explain
Not really, still one in every 2 people will be able to drive in college, the same as in highschool. They are mathematically equally likely! Hope that helps :)
No, Micah is not correct. Since there are equal numbers of people in each group who drive and who do not drive, the relative frequency for each is 50%. Because the relative frequencies are the same, there is no association between the variables.
3 if x is greater than or equal to 1 is nothing. That leaves us with if x<1. If you substitute in 1 for x, you get 3, but of course that isn't possible, so the range is , which is D.
