In a data set that was analyzed for personnel in the Department of Biochemistry at Virginia Polytechnic Institute and State University, three diets were given to a group of rats in order to study the effect of each on dietary residual zinc in the bloodstream. Five pregnant rats were randomly assigned to each diet group and each was given the diet on day 22 of pregnancy. The amount of zinc in parts per million was measured. The data are as follows. Determine if there is a significant difference in residual dietary zinc among the three diets. Use ? = 0.05. Perform a one-way ANOVA.
