A data set comparing a woman's shoe size to her height is represented by the table.

Shoe Size Height (inches)
7 60
9 72
10 65
7 68
9 69.5
10 70
12 75
12 61
13 68


What is the equation for the line of best fit for a woman's height, y, based on her shoe size, x?

a. y = −0.49x + 62.8
b. y = 0.49x + 62.8
c. y = 0.65x − 69.5
d. y = −0.65x − 69.5

Respuesta :

The line of best-fit for a woman's height, y, based on her shoe size, x is:

b. y = 0.49x + 62.8.

How to find the equation of linear regression using a calculator?

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points are given as follows:

(7, 60), (9, 72), (10,65), (7, 68), (9, 69.5), (10, 70), (12, 75), (12, 61), (13, 68).

Inserting these points into a calculator, the line of best-fit for a woman's height, y, based on her shoe size, x is:

b. y = 0.49x + 62.8.
