Tornadoes The following data represent the width (in yards) and length (in miles) of various tornadoes.

(a) Draw a scatter plot of the data, treating width as the independent variable.

(b) What type of relation appears to exist between the width and the length of tornadoes?

(c) Select two points and find a linear model that contains the points.

(d) Graph the line on the scatter plot drawn in part (a).

(e) Use the linear model to predict the length of a tornado that has a width of 450 yards.

(f) Interpret the slope of the line found in part (c).
