example solution showing the calculation of empirical probability New Principles of Counting example solution based on blood type CHAPTER 6 Discrete Probability Distributions Updated examples New exercises 9 10 17 18 24 25 49 66 67 68 69 Updated exercise 5 7 8 24 58 New example solution using the binomial distribution to predict purchase behavior with debit and credit cards CHAPTER 7 Continuous Probability Distributions New opening page and exercise Updated examples Revised example solution demonstrating the uniform probability distribution Revised example solution showing the calculation of the sample mean For all uniform distribution examples and exercises users are asked to compute the mean and standard deviation Revised example solution showing the calculation of the geometric mean Updated and revised exercise 1 2 5 7 8 11 12 28 Revised example solution showing the calculation of the sample standard deviation Updated Statistics in Action with most recent Major League Baseball data The section of the relative positions of the mean median and mode as well as the concept of skewness have been rewritten with new illustrations Updated exercises 21 23 25 30 31 32

defining the probability of a particular value of a continuous random variable to be zero Removed the section The Normal Approximation to the Binomial Using statistical software there is no need for approximations CHAPTER 8 Sampling Sampling Methods and the Central Limit Theorem New chapter title Sampling Sampling Methods and the Central Limit Theorem New section titled Research and Sampling This section now introduces the idea of sampling by discussing the research process i e posing a research question collecting data processing the data and making data based inferences and conclusions The
