A school principal wants to know the average number of extracurricular activity students in your school are involved in She signed each student and number from 1 to 415. Using a random number generator she selected 200 students and to be a part of the sample. She concluded that students are involved in an average of two extracurricular activities. Is the principles conclusion valid? No because 200 students in the sample is too large? Yes because every student had an equal chance to be part of the sample. The sample size also appears to be large enough. Yes because only those who have extracurricular activities were included in the sample? Or no because not all students in the sample have extracurricular activities.
