Question
To estimate the probability that a person is a cat owner, a random sample of 9 people is drawn. From the sample, it is determined that the relative frequency of cat owners is 0.44.What could be done to make the relative frequency a more accurate estimate of the probability ?
A. Increase the size of the random sample B. Use a simulation to estimate the empirical probability C. Use non random sample with a known empirical probability D. Use convenient sampling
(I choose A, but not sure ) To estimate the probability that a person is a cat owner, a random sample of 9 people is drawn. From the sample, it is determined that the relative frequency of cat owners is 0.44.

Explanation / Answer
(A) is the only correct choice. The standard error of estimate decreases with increase in sample size, making the point estimate more accurate.
