A) The desired confidence level is not given. B) The population is at least 10 times as large as the sample. C) n is so large that bot ...

A further appreciation can be gained by approaching this issue from the opposite direction; that is, by examining what percentage of the population is estimated to exhibit a score as low as an individual’s score when the standard procedure estimates it at 5%.
