Question

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: 758, 621, 518, 510, 492, 483 Stories, y: 51, 47, 46, 41, 37, 35 a) x=498 feet ​(b) x=644 feet ​(c) x=315 feet ​(d) x=734 feet

Answer 1

a)

predicted value =15.172+0.049*498=39.57

b)

predicted value =15.172+0.049*644=46.73

c)

not meaningful as 315 falls outside the range of x values

d)predicted value =15.172+0.049*734=51.14
