Please explain your work

A researcher wants to construct a linear model that can predict alertness based on the number of cups of coffee people drink. The Pearson correlation between alertness and cups of coffee is r = .65. Cu . s of Coffee Using the information provided in the table above, and the value of the correlation coefficient given, solve for the linear model representing number of cups of coffee (X) as a predictor of alertness (Y). Which of the following is the resulting linear model? O Y' = 0.78X + 2.64 O Y' = 0.55X + 3.51 O Y' = 0.55X + 0.71 O Y' = 0.78X - 0.62
