a.
Explanation of Solution
The interaction plot with pH being the trace factor is given as follows:
b.
Check whether there is interaction between the factors pH and temperature.
b.
Answer to Problem 17E
There is interaction between the factors pH and temperature.
Explanation of Solution
From the interaction plot obtained in Part (a), it is clear that the lines of pH I and pH II are not parallel to each other. Therefore, there is interaction between the factors pH and temperature.
c.
Calculate the main pH effects and the main temperature effects.
c.
Answer to Problem 17E
The main pH effects are
