Tutoring services: the community college survey of student engagement reports that 46% of the students surveyed rarely or never use peer or other tutoring resources. suppose that in reality 40% of community college students never use tutoring services available at their college. in a simulation we select random samples from a population in which 40% do not use tutoring. for each sample we calculate the proportion who do not use tutoring. if we randomly sample 100 students from this population, the standard error is approximately 5%. would it be unusual to see 46% who do not use tutoring in a random sample of 100 students?
