Suppose you are have the following null and alternative hypotheses for a test you are running: H 0 : p = 0.63 H a : p ≠ 0.63 Calculate the test statistic, rounded to 3 decimal places

Answer 1

The test statistic z = (phat - 0.63)/sqrt(0.63*0.37/sample size). You are missing information: the sample size and number of successes to compute the sample proportion (phat = number of successes/sample size).
