Apediatrician wants to determine the relationship that may exist between a child's height and head circumference. she randomly selects eleven 3-year-old children from her practice and measures their heights and head circumferences. according to the data, the linear correlation coefficient between the height and head circumference of a child is 0.918. compute the coefficient of determination, r^2

(a) 82%
(b) 84.3%
(c) 91.8%
(d) 82.6%

(B) 84.3%

Step-by-step explanation:

Correlation Coefficient (R) shows the direction and strength of the relationship between two variables. The correlation coefficient lies between -1 to +1.

The square of the correlation coefficient is called the Coefficient of Variation. It is denoted by R².

Here R = 0.918

Thus, R² = 0.843 which is equal to 84.3%

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
