Question:
12.46 The yield percentage Y of a certain precipitate depends on the concentration of the reactant and the rate of addition of diammonium hydrogen phosphate. Experiments were run at three different concentration levels and three addition rates. The yield percentages, with two observations per treatment, are listed in table below.
a Perform an analysis of variance, constructing all appropriate tests at the 5% significance level.
b Estimate the average yield percentage, in a 95% confidence interval, for the treatment at the middle level of both concentration and addition rate.
