Hypothesis tests based on ANOVA are good at letting us see if a continuous independent variable and a categorical dependent variable are related to each other. 4. In a regression model, the "y-intercept” (or "a”) tells you how strongly two variables are related. 5. R' tells you how much of the variance in Y is explained by your X-variables

Explanation / Answer
