Question

Use the value of the linear correlation coefficient r to find the coefficient of determination and the percentage ofthe total variation that can be explained by the linear relationship between the two variables. r = 0.885 (x = weight of male, y = waist size of male)

Answer 1

Explanation:

The coefficient of determination =
`r^(2) = 0.885^(2)` = 0.7832

It means about 78% variation in waist size of males can be explained by their weight and about 23% can not be explained.
