Atrue/false test has 40 questions. suppose a passing grade is 30 or more correct answers. test the claim that a student knows more than half of the answers and is not just guessing. assume the student gets 30 answers correct out of 40. use a significance level of 0.05. steps 1 and 2 of a hypothesis test procedure are given below. show step 3: finding the test statistic and the p-vahie and step 4, interpreting the results. step 1: h0: p = 0.50 ha: p > 0.50 step 2: choose the one-proportion z-test. sample size is large enough, because np0 is 40(0.5) = 20 and n(1 - p0) = 40(.5) = 20, and both are more than 10. assume the sample is random. step 3: compute the z-test statistic, and the p-value. z = (round to two decimal places as needed.) p-value = q (round to three decimal places as needed.)
