The data is from payscale.com. The variable "Cost" represents the four-year cost including tuition, supplies, room and board of attending the school. The variable "Annual ROI" represents the return on investment for graduates of the school. It essentially represents how much you would earn on the investment of attending the school. The variable "Grad Rate" represents the graduation rate of the school. Complete parts (a) through (f). Click the icon to view the data. (a) A scatter diagram between Cost and Grad Rate suggests a positive association between the two variables. Find the least-squares regression line treating Cost as the explanatory variable. y^=()x+1 (Round the slope to six decimal places. Round the constant to three decimal places.)
