Find the equation of the regression line for the given data. Then construct a scatter plot of the data and draw the regression line.​ (The pair of variables have a significant​ correlation.) Then use the regression equation to predict the value of y for each of the given​ x-values, if meaningful. The table below shows the heights​ (in feet) and the number of stories of six notable buildings in a city.

Height, x   Stories, y
768   52
628   48
518   45
511   43
491   38
478   35

(a) x=501 ft

(b) x=641 ft

(c) x=318 ft

(d) x=730 ft

Find the regression equation.

Answer #1

Find X⋅Y and X2 as it was done in the table below.

X Y X⋅Y X⋅X
768 52 39936 589824
628 48 30144 394384
518 45 23310 268324
511 43 21973 261121
491 38 18658 241081
478 35 16730 228484

Slope = 0.049

Intercept = 15.71

( a ) if x=501 then

y = 15.71 + 0.049 ( 501 )

= 40.259

= 40

( b ) if x=641 then

y = 15.71 + 0.049 ( 641 )

= 47.119

= 47

( c ) if x=318 then

y = 15.71 + 0.049 (318 )

= 31.292

= 31

( d ) if x=730

y = 15.71 + 0.049 (730 )

= 51.48

= 51
