Explanation Given info: The values of p = 0.8 and n = 20 . Calculation: The value is p = 0.8 . The value of q is 0.2 (1–0.2). The total number n is 20. Requirement check: Condition 1: n p ≥ 5 Condition 2: n q ≥ 5 Condition 1: n p ≥ 5 Substitute 20 for n and 0.8 for p in the np . n p = 20 × 0.8 = 16 Thus, the given requirement 16 ≥ 5 is satisfied. Condition 2: n q ≥ 5 Substitute 20 for n and 0

To obtain: P ( more than 11 ) if requirements of n p ≥ 5 and n q ≥ 5 are both satisfied otherwise state the normal approximation is not appropriate if n p < 5 or n q < 5 .

Solution Summary: The author explains that the normal approximation should not be used because the requirement nq5 is not satisfied.
