9. Employee Retention. Employee retention is a major concern for many companies. A sur- vey of Americans asked how long they have worked for their current employer (Bureau of Labor Statistics website). Consider the following example of sample data of 2000 college graduates who graduated five years ago. Time with Current Employer (years) Number 1 506 2 390 3 310 4 218 5 576 Let x be the random variable indicating the number of years the respondent has worked for her/his current employer. a. Use the data to develop an empirical discrete probability distribution for x. b. Show that your probability distribution satisfies the conditions for a valid dis- crete probability distribution. c. What is the probability that a respondent has been at her/his current place of employment for more than 3 years?

The General Social Survey is an annual survey given to a random selection of about 1500 adults in the United States. Among the many questions asked are "What is the highest level of education you've completed?" and "If you're employed full-time, how many hours do you spend working at your job during a typical week?" In a recent year, 1079 respondents answered both questions. The summary statistics are given in the chart below. (The sample data consist of the times, in hours per week, that were given by the respondents.) Sample Sample Sample size Groups mean variance Less than h.s.
