Explanation Given info: The values of p = 0.7 and n = 12 . Calculation: The value is p = 0.7 . The value of q is 0.3 (1–0.7). The total number n is 12. Requirement check: Condition 1: n p ≥ 5 Condition 2: n q ≥ 5 Condition 1: n p ≥ 5 Substitute 12 for n and 0.7 for p in the np . n p = 12 × 0.7 = 8.4 Thus, the given requirement 8.4 ≥ 5 is satisfied. Condition 2: n q ≥ 5 Substitute 12 for n and 0

To obtain: P ( fewer than 8 ) 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 requirement nqge 5 is not satisfied, hence the normal approximation should not be used.
