The article Characterization of Highway Runoff in Austin,Texas, Area (J. of Envir. Engr., 1998: 131137) gave ascatter plot, along with the least squares line, ofand for aparticular location. The accompanying values were readfrom the plot.a. Does a scatter plot of the data support the use of the simplelinear regression model?b. Calculate point estimates of the slope and intercept of thepopulation regression line.c. Calculate a point estimate of the true average runoff volumewhen rainfall volume is 50.d. Calculate a point estimate of the standard deviation s.e. What proportion of the observed variation in runoffvolume can be attributed to the simple linear regressionrelationship between runoff and rainfall?
