heavy dose of the bacterium. Another group of 55 mice, which had not vaccinated, was
challenged with the same dose. Twenty nine mice in the vaccine group contracted the
disease, and thirty five in the control group became ill. Test for effectiveness of the
vaccine. (Chi square at 5% level of significance is 3.841)
