3.12. A pharmaceutical manufacturer wants to investigate the bioactivity of a new drug. A completely randomized single-factor experiment was conducted with three dosage levels, and the following results were obtained. Dosage 20 g 30 g 40 g 24 37 42 Observations 28 44 47 37 31 52 30 35 38 (a) Is there evidence to indicate that dosage level affects bioactivity? Use a = 0.05. (b) If it is appropriate to do so, make comparisons between the pairs of means. What conclusions can you draw? (c) Analyze the residuals from this experiment and com- ment on model adequacy.
