Question

Find the equation of the regression line for the given data. Then construct a scatter piot of the data and draw the correlation.) Then use the rogression equation to predict the value of 6 men regression line. (The pair of variables has a significant y for each of the given x-values, if meaningful. The table shows the shoe size and heights (in) for (a) x-size 10.5 (c) x-size 16.0 (b) x- size 10.0 (d) x- size 9.5 reen 68 Find the regression equation (Round to three decimal places as needed.) Construct a scatter plot of the data and draw the regression line. Plot shoe size on the horizontal axis and OA. height on the vertical axis. Choose the correct gragh below B. O c. OD. Click to select your answer(s)

Explanation / Answer

The regression equation is
Y-hat = 52.8 + 1.45 X

Correct answer: Option (B) Scatter diagram

a) If X = 10.5 then Y-hat = 52.8 + 1.45(10.5) = 68.025
Correct answer: Option (B)
b) If X = 10 then Y-hat = 52.8 + 1.45(10) = 67.3
Correct answer: Option (C)

C) If X = 16 then Y-hat = 52.8 + 1.45(16) = 76
Correct answer: Option (B)

D) If X = 9.5 then Y-hat = 52.8 + 1.45(9.5) = 66.575
Correct answer: Option (B) 66.6
