(10 points) Because elderly people may have difficulty standing to have their height measured, a study looked at the relationship between overall height and height to the knee. Here are data (in centimeters) for five elderly men:

Knee Height x 56 44 41 44 55
Height y 190 150 145 165 174

What is the equation of the least-squares regression line for predicting height from knee height?

Step-by-step explanation:

We are given the following in the question:

Knee Height(x):  56     44      41     44     55

        Height(y):  190   150   145   165   174

The least square regression equation is given by:

where

Putting values, we get,

Thus, the regression equation is:

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

b and c are the correct answers.
