13 5 points Suppose we are testing this null hypothesis regarding P: : P 0.50 In our sample of 100 randomly selected observations, we observe a sample proportion W) of 0.59. If we are comfortable with a value for a of 0.05, the critical value for our test statistic will be and we should O Z = -1.96 orZ=+1.96; reject Ho O Z = +1.96; not reject Ho O Z = +1.645; reject HO O Z = -1.645; not reject Ho Next Previous
