A student organization reports that, of a random sample of 300 college undergraduates, 95% attend all their classes during the first week of the semester and 15% d not attend all their classes during the first week. We know there is a mistake in this report because O A stratified sample would have been less prone to error O It's very unlikely that 15% of students didn't attend all their classes during the first week O There is always a possibility of response bias O 95% plus 15% adds up to more than 100%
