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 a = 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 (Pv)∞ - 1 1/T, where is the vapor pressure of water. Repeat parts (a)€“(d). Using an appropriate transformation.
