3-14 .3 A pharmaceutcal manufacturer wants to investgate the bioactvity of a new drug. A completely randomized single factor experiment was conducted with three dosage levels, and the following results were obtained. a.Is there evidence to indicate that dosage level affects bioactvity? Use α =0.05 b. If it is appropriate to do so, make comparisons between the pairs of means. What conclusions can you draw? c.
