Answer:
c) 
Step-by-step explanation:
Equation for regression line of y on x is given as

where
= predicted value
m = slope of line
b = intercept
m and b are found as

r = correlation coefficient = 0.88
Sx = standard deviation for independent variable x = 13
Sy = standard deviation for dependent variable y = 27
= mean value of independent variable x = 21
= mean value of dependent variable y = 55
Substituting these values in (2) and (3)


Putting these values of m and b in (1)
