The assumption of sample size (N) larger than 1,000 is not necessary for a test of hypothesis with a single sample mean. It is a common misconception that a large sample size is always necessary, but in reality, the sample size should be appropriate for the research question and the level of precision desired. The other assumptions listed (representative sample, normal sampling distribution, and interval-ratio level of measurement) are all necessary for a test of hypothesis with a single sample mean.
