Statistics 371-001 Spring 2009 Dr. Laughlin HOMEWORK 2 Due February 12, 2009, 5:00 p.m. (in folder outside my office, Room 1227 MSC) Page 39, Problems 2.32, 2.33, 2.34 and 2.39. For 2.33 and 2.34, be sure to include consideration of whether either of the graphs should be a modified boxplot and specify how large or small an observation would have to be to be an outlier in each group (men or women). L.1. Write brief definitions of deviation, variance and standard deviation for a sample. Page 48, Problem 2.41b and 2.41c. Show and label the four steps required for calculating the problem (i.e., don’t just push the sd button on your calculator – although you can use that as a check of your work!!); see page 41, steps a to d (it’s actually 5 steps if you count finding the deviations). Find the mean, variance and standard deviation of the following sample of n = 5 scores:

Page 48, Problem 2.47, 2.48 and 2.49. For 2.48, the mean and SD are given but calculate them and show the calculations. Page 67, Problem 2.74. Page 77, Problem 3.2. Page 83, Problem 3.5. Also, draw probability trees and show all probabilities. Page 87 - 88, Problems 3.7, 3.9, and 3.10. Also, draw probability trees and show all probabilities. Page 93, Problem 3.13. Set up the problems using probability notation such as in the two steps of the definition on page 90 and show as many steps as possible using numbers such as in the examples on page 94. Page 95, Problem 3.15. Set up the problems using probability notation and show as many mathematical steps as possible. Page 101 – 102, Problems 3.18, 3.19 and 3.20....
