Quizplus · Accepted Answer

The one-proportion z-interval procedure is appropriate when the sample size is large enough and the success-failure condition is met (np ≥ 10 and n(1-p) ≥ 10). Here, with x = 104 successes out of n = 110, both conditions are satisfied (104 > 10 and 6 > 10), indicating the procedure is appropriate.
