Choose an answer, then open the working. Each explanation says why the right answer is right and why the others are not.
A Veterinary Service must show freedom from a disease in a large population. Assuming a perfect test, a design prevalence of 5% and 95% confidence, how many animals must be sampled at random? (Use n = ln(1 − C)/ln(1 − P).)
D. 59
n = ln(0.05)/ln(0.95) = −2.996/−0.0513 = 58.4, rounded up to 59. Rounding down to 58 gives less than 95% confidence; 20 is 1/0.05; 95 confuses the confidence level with sample size.
