Sailboat enthusiasts believe that the wind speed (x, in miles per hour) is linearly related to (downwind) boat speed (y, in knots). For wind speeds between 10 and 30 mph and Hobie catamarans, the following data were recorded.
a. Construct a scatter plot for these data.
b. Find the estimated regression line. Add a graph of the estimated regression line to the scatter plot in part (a).
c. Estimate the mean speed of a Hobie catamaran for a wind speed of 18 mph.
