Question 8

(CO 6) Find the regression equation for the following data set

x915241319

y12837912

Group of answer choices

= 2.68x - 0.44

= 0.44x + 2.68

= -0.44x + 2.68

= -2.68x + 0.44

Question 3

y50801107844575144

Group of answer choices

= 45.69x + 0.09

= 45.69x - 0.69

= 0.09x + 45.69

cannot be determined
