Suppose we want to estimate the proportion of college students who have a high level of stress. In a previous homework assignment, we looked at a sample of 253 college students and found that 56 ofthem had high levels of stress.1 What proportion of students in the sample had a high level of stress? Round to four decimal places. Hint 0.2213 I o' lOnyper, 5., Thacher, P., Gilbert,l., & Gradess, S. (2012). Class start times, sleep, and academic performance in college: A path analysis.

It is the measure of sample-to-sample variability. We will use the standard error to help us convey information about the accuracy of our point estimate] Calculate the estimated standard deviation for the sample proportion for the scenario in Question 1.
