Question

If y=11,x=6 and byx = 1.25, then the regression equation of y on x is

a) y=x+1

b) y-1.25x+2

c) y=1+x

d) y-1.25 x +3.5R

Answer 1

Answer:

Option d) is correct answer.

Step-by-step explanation:

Given-

y = 11 , x = 6 and byx = 1.25

lets verify every option one by one-

a) y = x+1

y = 6+1

y = 7

11 ≠ 7 , Therefore, option (a) is incorrect answer.

b) y = 1.25x+2

y =1.25× 6+2

y = 7.5+2

11 ≠ 9.5, Therefore, option b) is incorrect answer.

c) y=1+x

y = 1+6

y = 7

11 ≠ 7  Therefore, option c) is incorrect answer.

d) y=1.25 x +3.5

y = 1.25× 6+3.5

y = 7.5+3.5

11 = 11  Therefore, option d) is correct answer.
