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 29 years. Is the result within 5 years of the actual Best Actor winner, whose age was 43 years?

Find the equation of the regression line.
ModifyingAbove y with caretyequals=nothingplus+(nothing)x
(Round the constant to one decimal place as needed. Round the coefficient to three decimal places as needed.)
Let x = Best Actress , y = Best Actor
Find X⋅Y and X^{2} as it was done in the table below.
X  Y  X⋅Y  X⋅X 
29  43  1247  841 
29  36  1044  841 
28  37  1036  784 
62  46  2852  3844 
33  53  1749  1089 
33  46  1518  1089 
47  60  2820  2209 
29  52  1508  841 
61  39  2379  3721 
22  55  1210  484 
45  43  1935  2025 
51  31  1581  2601 
Find the sum of every column:
∑X=469 , ∑Y=541 , ∑X⋅Y=20879 , ∑X^{2}=20369
constant = 50.2
coefficient = 0.130
so equation of the regression line. is
y = 50.2  0.130 x
