Use the data in Epinuneq.dat to run three separate one-way analyses of variance, one at each retention interval. In each case, test the null hypothesis that the three dosage means are equal. Have your statistical package print out the means and standard deviations of the three dosage groups for each analysis. Now run a separate analysis testing the hypotheses that the three Interval means are equal. In this case you will simply ignore Dosage.
