Input the proportion p you are testing, the number of successes x, sample size, and the type of test you are conducting (right tail since Ha is greater than). Highlight Calculate and press ENTER. The test results displayed include the test statistic (z=.913), the p–value (p = .181), the sample proportion (= .667), and the sample size (n = 45).
