It is thought that 63.7% of the student body owns a school sweatshirt. A student reports that from a simple random sample of 1000 students, 637 own a school sweatshirt. Which of the following is most likely true? A) this should be trusted since it matches exactly what was thought B) Thus, 6.37% of the sample own a school sweatshirt, which refutes the original thought C)The student didn't get IRB approval, so the results are invalid D) It is highly unlikely that an SRS would yield results exactly matching what was expected
