Note: The GMAT is a standardized test for entry into business school. For graduates of top business schools, GMAT scores range between 650 and 800. The advisor conducts a linear regression analysis and produces the following model: y= -72040+228x The advisor also calculates a few other items, including the correlation coefficient: r = 0.82 Answer the following questions: 1. Approximately what percentage of the sample variation in SALARY can be explained by using GMAT in this linear model? Enter your answer here. Do not round. The percent symbol is provided: 2.
