The equation of the line of best fit for variables x and y is (y = 19.33 + 0.42x), where x is the independent variable. Estimate the value of y when x = 15.
-
A.
18.91 -
B.
19.75 -
C.
25.63 -
D.
38.23
Correct Answer: Option C
Explanation
(y = 19.33 + 0.42x)
(text{The value of y when x = 15} = 19.33 + (0.42 times 15))
= (19.33 + 6.30)
= 25.63
