Explanation / Answer

As per the gien information the responce variable is missing hence we gave both the Y on X model information and also X on Y model information. Here we consider the GMAT variable as the Y variable and GPA variable as the X variable

GMAT on GPA model:

Y=100.374+58.561X

GPA on GMAT model:

X=0.097+0.008Y

R codes:

data1<-read.csv("C:/Users/admin/Documents/Book3.csv")
model<-lm(y~x,data<-data1)
round(model$coefficients,3)

model1<-lm(x~y,data<-data1)
round(model1$coefficients,3)
