In a random sample of 100 people, 40% of them are non-vegetarian. What proportion of the whole population is non-vegetarian?
| A. | 54.3% |
| B. | 36.9 to 37.9% |
| C. | 30.6% |
| D. | 54.7% to 25.3% |
Answer : D Explanation : P = 40/100 = 0.4 q = 1 - p or 0.6 = 1 - 0.4 Standard error = √npq = √(100 x 0.4 x 0.6) = √24 = 4.899 3 x 4.899 ± 40 = 54.7 to 25.30% are non-vegetarian, Hence the answer is (d).
