Naddika [18.5K]

Answer:

112

Step-by-step explanation:

Given that in a study of the stability of IQ scores, a large group of individuals is tested once at age 18 and again at age 35.

Age 18: average score = 100, SD = 15

Age 35: average score = 100, SD = 15, r = 0.80

Let us obtain regression equation of y on x.

Let y be the scores at age 35 and x at age 18

Slope = r(s_y/s_x) = 0.8(\frac{15}{15} )=0.80

The line passes through (100,100) being average of x and y

Hence regression line would be

y-100=0.8(x-100)\\y = 0.8x+20

a) Here given that x =115

Hence y=0.80(115)+20\\=112

the average score at age 35 for all the individuals who scored 115 at age 18, would be 112.

b) Prediction also would be the same 112.
