Problem #3: A high-risk group of 808 male volunteers was included in a major clinical trial testing a new vaccine for type B hepatitis. The vaccine was given to 328 pers randomly selected from the group, and the others were injected with a neu substance (placebo). 15 of the vaccinated people and 33 of the nonvaccinated o later got the disease. We wish to test the hypothesis that the probability of getting type B hepatitis different (higher or lower) for people who were vaccinated compared with peo who were not, using the 5% significance level. (a) If we use the contingency table method to test this hypothesis, find the values in the expected table. (b) Find the value of the test statistic (using the contingency table method). (c) Find the critical value (using the contingency table method).
