The following regression equation and correlation coefficient were calculated using minitab for the bivariate data age of men and their weight.

Weight = -500 + 16.6Age

Pearson correlation of Age and Weight = 0.203

Which of the following is true?
A) The correlation coefficient shows a low correlation value, therefore, any prediction would not be very accurate
B) The youngest man in this sample must have been 16.6 years old
C) Each year men gain more than 16 pounds
D) The regression equation must be miscalculated because it show a negative slope, meaning as age increases weight decreases and the correlation coefficient shows the opposite
E) I could use this equation to accurately predict the weight of a 75 year old man
