Unit 7: Linking Probability to Statistical Inference (Due 7/2/18) Unit 7 Quiz: Linking Probability to Statistical Inference Choose the BEST answer. 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% o com munity 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 tutonng. For each sample we calculate the proportion who do not use tutoring If we randomly sample 00 students from this population, the standard error s approximately 52 Would it be unusual to see 46% who do not use tutoring in a random sample of 100 students? Yes this would be unusual because 46% is more than one standard error from the mean it is very rare for a sample to be more than one standard error from mean No, this would not be unusual because the error is only 6%. No, this would not be unusual because 46% is only 12 standard errors from 40 Yes, this would be unusual because 46% is 6% higher thani 40% ?Previous Next >
