For a sample proportion, the success-failure condition must be met to use a normal approximation. If a study finds that 20% of a sample of 200 people prefer a new product, does the sample size meet the success-failure condition? (1 point) O Yes, because both np and n(1-p) are at least 10. O No, because np is not at least 10. O Yes, because n is greater than 30.
