Question

Find the regression​ equation, letting the first variable be the predictor​ (x) variable. Using the listed​ actress/actor ages in various​ years, find the best predicted age of the Best Actor winner given that the age of the Best Actress winner that year is 31 years. Is the result within 5 years of the actual Best Actor​ winner, whose age was 49 ​years? Best Actress 29 30 30 63 31 35 43 29 60 22 46 57 Best Actor 43 37 39 47 49 49 58 50 39 54 45 32 Find the equation of the regression line. ModifyingAbove y with caret equalsnothingplus​(nothing ​)x ​(Round the constant to one decimal place as needed. Round the coefficient to three decimal places as​ needed.)

Answer 1

This problem is solved by using R

Output is

Estimated least square regression equation is

Y = 52.0 - 0.172 X

Now, find the best predicted age of the Best Actor winner given that the age of the Best Actress winner that year is 31 years.

Therefore, x = 31

Y = 52.0 - 0.172*31

Y = 46.67 age
