9) A Null Hypothesis (H0): No relationship exists between physical activity and chemistry
midterm exam scores

10) A Null Hypothesis (H0): No relationship exists between class ranking and caffeine consumption.
Alternative Hypothesis (HA): A relationship exists between class ranking and caffeine consumption.
11) Type I error is essentially a false positive error meaning we are rejecting the Null Hypothesis
when it this when it should not be rejected. In this case, the Null Hypothesis (H0) would be: The
is no relation between enrollment status and alcohol consumption. While the Alternative Hypothesis (HA) would be: The is a relation between enrollment status and alcohol consumption.
If the truly isn’t a relationship between these variables, and we decide to conclude that there is,
we would’ve made a Type I error.
