The article €œCalifornia State Parks Closure List Due Soon€ (The Sacramento Bee, August 30, 2009) gave the following data on y = number of employees in fiscal year 2007€“ 2008 and x = park size (in acres) for the 20 state park districts in California:

a. Construct a scatterplot of these data.
b. Find the equation of the least squares regression line. Do you think this line would give accurate predictions?
Explain.
c. Delete the observation with the largest x value from the data set and recalculate the equation of the least squares regression line. Does this observation have a big effect on the equation of the line?
