Given data on shoulder girth and height of a group of individuals. The mean shoulder girth is 107.20 cm with a standard deviation of 10.37 cm. The mean height is 171.14 cm with a standard deviation of 9.41 cm. The correlation between height and shoulder girth is 0.67.
Write the equation of the regression line for predicting height.

(a) corresponds to (2) since r = 0.49 implies a positive correlation and fairly linear relation and scatter plot (2) is the only plot which has positive correlation from among the other plots

Step-by-step explanation:

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
