In order to become a certified public accountant (CPA), you must pass the Uniform CPA Exam. Many states require a minimum of 150 semester hours of college education before a candidate can sit for the CPA exam. However, traditionally, colleges only require 128 semester hours for an undergraduate degree. A study of whether the "extra" 22 hours of college credit is warranted for CPA candidates was published in the Journal of Accounting and Public Policy (Spring 2002). For one aspect of the study, researchers sampled over 100,000 first-time candidates for the CPA exam and recorded the total semester hours of college credit for each candidate. The mean and median for the data set were 141.31 and 140 hours, respectively. Interpret these values. Make a statement about the type of skewness, if any, that exists in the distribution of total semester hours.
