Answer:
D) 356
Explanation:
ME = Z x √[(P x Q) / N]
- margin of error (ME) = 4%
- 90% confidence level (Z) = 1.645 (by convention)
- P = 70% of apples exceed Grade A
- Q = 30% of apples do not exceed Grade A
- N = sample size = ?
0.04 = 1.645 x √[(0.7 x 0.3) / N]
0.04 = 1.645 x √(0.21 / N)
0.04 = 1.645 x 0.458 / √N
0.04 = 0.7538 / √N
√N = 0.7538 / 0.04 = 18.84
N = 18.84² = 355.2 ≈ 356 (there is no 0.2 apples, you must round up)
