Like many businesses, The National Hurricane Center also participates in a program to improve the quality of data and predictions by government agencies. They report their errors in predicting the path of hurricanes. The following scatterplot shows the trend in 48- hour tracking errors since 1970. (www.nhc.noaa.gov/verification/pdfs/1970-present_OFCL_ATL_verification/pdfs/1970-present_OFCL_ATL_annual_trk_errors_noTDs. pdf)

a) Interpret the slope and intercept of the regression model.
b) Interpret se in this context.
c) If the Center had a goal of achieving an average tracking error of 50 nautical miles by 2015, will they make it? Explain.
d) Use technology to compute the Durbin- Watson statistic and comment.
e) What cautions would you state about your conclusion?
