In a recent study of the prevalence of sexually transmitted diseases, a simple random sample of 35,000 Americans were selected and it was found that 20.1% reported having at least one STD. A hypothesis test for a difference from the expected 20% was found to be highly significant, though the difference is quite small. The explanation is that O All of the above O the sample size is very large. O the value of 20.1% is large compared to the hypothesized value of 20%. O it was an aberrant sample.
