Question

The average driving distance​(yards) and driving accuracy​(percent of drives that land in the​fairway) for 8 golfers are recorded in the table to the right. Complete parts a through e below.		Player	Distance​ (yards)	Accuracy​ (%)
		1	316.1	44.6
		2	303.3	51.7
		3	309.4	47.5
		4	311.6	40.6
		5	295.3	55.4
		6	290.4	58.9
		7	295.8	56.2
		8	304.3	49.5

a. Write the equation of a​ straight-line model relating driving accuracy​ (y) to driving distance​ (x). Choose the correct answer below.

A.y equals beta 1 xy=β1x

B.y equals beta 1 x squared plus beta 0y=β1x2+β0

C.y equals beta 1 x plus epsilony=β1x+ε

D.y equals beta 0 plus beta 1 x plus epsilony=β0+β1x+ε . Your answer is correct

.b. Fit the​ model, part

a​, to the data using simple linear regression. Give the least squares prediction equation.ModifyingAbove y with caretyequals=
