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 30 years. Is the result within 5 years of the actual Best Actor​ winner, whose age was 48 years?

	Best Actress	28	30	29	62	32	35	43	30	62	22	44	53

Best Actor	42	36	37	43	52	46	61	48	39	56	45	34

yhat= __+(__)x

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

Answer 1

yhat =51.603+(-0.171)*x

from above equation: the predicted value =46 (please try 45 if correlation table or significance level 0.05 is mentioned)

the result is within 5 years of the actual Best Actor​winner, whose age was 48 years
