Suppose the correlation coefficient describing how the height of teenage boys predicts their weights is 0.85. what is the coefficient of determination, 2 , and what does it mean in context? a 2 is 0.7225. 72.25% of the variation in weights of teenage boys can be explained by their height. b) 2 is 0.7225. 72.25% of the variation in heights of teenage boys can be explained by their weight. c) 2 is 0.85. 85% of the variation in heights of teenage boys can be explained by their weight. d) 2 is 0.85. 85% of the variation in weights of teenage boy

Option A) 72.25% of the variation in weights of teenage boys can be explained by their height.

Step-by-step explanation:

Coefficient of determination:

We are given that correlation coefficient of height of teenager and their weights is 0.85.

Option A) is the correct interpretation of coefficient of determination.

72.25% of the variation in weights of teenage boys can be explained by their height.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
