In a survey, 15 high school students said they could drive and 15 said they could not. Out of 60 college students surveyed, 30 said they could drive. Micah concluded that if someone is in college, that means the person is more likely to drive. Is Micah’s conclusion correct? Explain.

No

Step-by-step explanation:

In the high school survey, it said 15 could drive and 15 could not. This means that 1/2 could drive and 1/2 could not.

In the college survey, it said that 30 could drive out of 60. That is still 1/2 of the people asked.

The ratios are the same so therefore Micah's conclusion is wrong

sample answer

No, Micah is not correct. Since there are equal numbers in the group that drive and the group that doesn’t drive, the relative frequency for each is 50%. Because the relative frequencies are the same, there is no association between the variables.
