Do students with higher college grade point averages (GPAs) earn more than those graduates with lower GPAs? With data on college GPA and salary 10 years after graduation, you estimate the following regression: Salary = −110, 210 + 72, 990.5GPA (22,864) (7,037.4) You want to test the statistical significance of the slope coefficient. What is the value of your test statistic? (Enter your answer rounded to two decimal places). What is your conclusion? At 0.01 significance level, the evidence suggests that there (is/is not) a significant statistical positive relationship between the two variables.
