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

6060

years. Is the result within 5 years of the actual Best Actor​ winner, whose age was

3838

​years?

Best Actress	2828	2929	3030	6262	3434	3434	4545	2929	6060	2121	4343	5252
Best Actor	4242	3737	3636	4545	5050	4848	6060	5252	3838	5454	4545	3535

Find the equation of the regression line.

​(Round the constant to one decimal place as needed. Round the coefficient to three decimal places as​ needed.)

Answer 1

Data

Using Excel

data -> data analysis -> regression

y^ = -50.4 -0.135 x {note negative sign in both slope and intercept}

x = 60

y^ = 42.33

yes, it is within 5 years of 38
