The vapor pressure of water at various temperatures is in Table E11-11:

(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 y_i. What do you conclude about model adequacy?

(e) The Clausius€“Clapeyron relationship states that ln(P_v)ˆ ˆ’ 1/T where P_v is the vapor pressure of water. Repeat parts (a)€“(d) using an appropriate transformation.
