Tall Buildings The scatterplot shows information about the world’s tallest 169 buildings. “Stories” means “Floors.”

a. What does the trend tell us about the relationship between stories and height (feet)?

b. The regression line for predicting the height (in feet) from the number of stories is shown above the graph. What height would you predict for a building with 100 stories?

c. Interpret the slope.

d. What, if anything, do we learn from the intercept?

e. Interpret the coefficient of determination.

(This data set is available at the text’s website, and it contains several other variables. You might want to check to see whether the year the building was constructed is related to its height, for example.)
