A study of the top 75 MBA programs attempted to predict the average starting salary (in $1000’s) of graduates of the program based on the amount of tuition (in $1000’s) charged by the program. The results of a simple linear regression analysis are shown below:

◦ For every $1000 increase in the tuition charged by the MBA program, we estimate that the average starting salary will increase by $1474.94.
◦ For every $1474.94 increase in the tuition charged by the MBA program, we estimate that the average starting salary will increase by $18,184.90.
◦ For every $1000 increase in the average starting salary, we estimate that the tuition charged by the MBA program will increase by $1474.94.
◦ For every $1000 increase in the tuition charged by the MBA program, we estimate that the average starting salary will decrease by $1474.94.
