The vapor pressure of water at various temperatures follows:

(a) Draw a scatter diagram of these data. What type of relationship seems appropriate in relating
y
to
x?

(b) Fit a simple linear regression model to these data.

(c) Test for significance of regression using α = 0.05. What conclusions can you draw?

(d) Plot the residuals from the simple linear regression model versus
. What do you conclude about model adequacy?

(e) The Clausis-Clapeyron equation states that ln
 where P_vis the vapor pressure of water. Repeat parts (a)–(d). using an appropriate transformation.
