and wind velocity (x).
(a) Draw a scatter diagram of these data. What type of rela-
tionship seems appropriate in relating y to x?
(b) Fit a simple linear regression model to these data.
(c) Test for significance of regression using a = 0.05. What
conclusions can you draw?
(d) Plot the residuals from the simple linear regression model
versus y, and versus wind velocity x. What do you con-
clude about model adequacy?
(e) Based on the analysis, propose another model relating y to.x.
Justify why this model seems reasonable.
(f) Fit the regression model you have proposed in part (e).
Test for significance of regression (use a = 0.05), and
graphically analyze the residuals from this model. What
can you conclude about model adequacy?
