If you’re trying to prove that the vaccine is effective (lower incidence of polio with the vaccine like the class discussion), what’s your test statistic and your conclusion at the 1% level of significance?
a. T test = -2.364 and fail to reject the null
b. F test = 0.553 and fail to reject the null
c. Z test = -2.364 and reject the null
d. T test = 2.364 and fail to reject the null
e. Z test = -2.701 and reject the null
