Linear regression was used to estimate this relationship, and the:

a) Coefficient of determination was calculated
b) Correlation coefficient was ignored
c) Causation was established
d) Residuals were minimized

Final answer:

The question is about a study on the relationship between SAT scores and state-level characteristics. Linear regression was used to estimate this relationship and the coefficient of determination was calculated.

Step-by-step explanation:

The subject of this question is Mathematics. The question asks about a recent study on the relationship between SAT scores and U.S. state-level characteristics.

In this study, linear regression was used to estimate the relationship between average SAT scores and the percent of high school seniors who took the SAT within a state.

The coefficient of determination, also known as the R-squared value, was calculated to determine how well the linear regression model explains the variation in average SAT scores.
