It is believed that, the average numbers of hours spent studying per
day (HOURS) during undergraduate education should have a
positive linear relationship with the starting salary (SALARY,
measured in thousands of dollars per month) after graduation. Given
below is the Excel output for predicting starting salary (Y) using
number of hours spent studying per day (X) for a sample of 51
students.
