Problem 77E

Testing a new pain-reliever tablet. Refer to the Tropical Journal of Pharmaceutical Research (June 2003) study of the impact of binding agent, binding concentration, and relative density on the mean dissolution time of pain-relief tablets, Exercise 9.14 (p. 493). Recall that the binding agent was set at two levels (khaya gum and PVP), binding concentration at two levels (.5% and 4.0%), and relative density at two levels (low and high); thus, a 2 * 2 * 2 factorial design was employed. The sample mean dissolution times for the treatments associated with the factors binding agent and relative density when the other factor (binding concentration) is held fixed at .5% are   ,  and  Do the results suggest there is an interaction between binding agent and relative density? Explain.
