Question

The height (sidewalk to roof) of notable tall buildings in America is compared to the number of stories of the building (beginning at street level).

Height (in feet)	Stories
1050	58
428	29
362	25
529	40
790	60
401	22
380	38
1454	110
1127	100
700	46

Part a) Calculate the least squares line. Put the equation in the form of: ŷ = a + bx.

Part b) Find the correlation coefficient r.

Part c) Based on the least squares line, adding an extra story adds about how many feet to a building?

Part d) What is the slope of the least squares (best-fit) line? (Round your answer to three decimal places.)
Interpret the slope.

As the  ---Select--- number of stories height of the building increases by one unit, the  ---Select--- height number of stories of the building increases by   ---Select--- stories feet .
