Use the following information to answer the question. A random sample of 30 married couples were asked to report the height of their spouse and the height of their biological parent of the same gender as their spouse. The output of a regression analysis for predicting spouse height from parent height is shown. Assume that the conditions of the linear regression model are satisfied.

-If the intercept was 0 and the slope was 1, what would that say about the association?
A)It would mean that on average, the spouse is 1 inch taller than the parent.
B)It would mean that the spouse height should not be predicting using parent height.
C)It would mean that on average, the spouse and the parent are the same height.
D)None of these.

If the intercept is 0 and the slope is 1, it indicates a perfect linear relationship where the dependent variable (spouse height) is equal to the independent variable (parent height), meaning they are on average the same height.
