Document Summary

This review contains several problems from chapters 5, 6, 7, and 8. Please note that all topics will not necessarily be covered in this review. For a full review of topics, please review suggested homework problems and course notes: a college professor wants to learn if there is a relationship between time spent on homework and the percent of the homework completed. Let x be the number of weeks after being distributed that an assignment is turned in, and y as the percent of the assignment that is completed. Find the variance of each marginal distribution: find the covariance of x and y, find the correlation of x and y, let (cid:2869),(cid:2870), , be a random sample from a distribution with pdf (cid:1858)(cid:4666)(cid:1876);(cid:4667)=(cid:2869)(cid:1857) / with (cid:882)
