What is the minimum probability of success needed in order to use normal approximations for an estimate about a population, given a sample size of 135? Round your answer to the nearest integer.

1 answer

In general, the minimum probability of success needed to use normal approximations for an estimate about a population is considered to be at least 10%. However, some statisticians argue that a minimum probability of success of 5% may also be acceptable.

Therefore, for a sample size of 135, the minimum probability of success needed would be 10%.

Rounded to the nearest integer, the answer would be 10%.
