Question

13. 61x + 150.87. The least squares regression equation for the data below is y Fat (9) 6 7 10 19 36 20 27 Calories 276 260 220 388 430 550 633 Using the equation, estimate the amount of fat in grams if you consume 721 calories. O 42 g О 9964 g O 64 g 8925 g

Answer 1

y = 13.61x + 150.87

where:

y: Calories

x: fat (g)

To estimate the amount of fat if you consume 721 calories, you have to replace y = 721 into the equation and solve for x.

721 = 13.61x + 150.87

721 - 150.87 = 13.61x

570.13 = 13.61x

570.13/13.61 = x

42 grams = x
