Several major corporations have had to pay millions of dollars to settle "gender discrimination" lawsuits. As a result of these rulings, companies are very concerned with the parity of pay of their employees. Wal-Mart faced the nation's largest workplace gender-bias lawsuit. In June 2004, U.S. District Court Judge Martin Jenkins granted class-action status to 1.6 million current and former female Wal-Mart employees who charged the company with paying women less and offering them fewer opportunities for promotion. (40 points total) The following table shows the salaries of 20 females and 20 male Wal-Mart employees. Every effort was made in pairing the data on similar characteristics such as same amount of experience, same responsibilities, same job title, same years at the company, etc. Pair 1234 OPY 5 6 7 8 Female Male $43,800 $44,000 $35,500 $36,000 $39,700 $38,000 $38,000 $42,000 $36,500 $37,000 $34,900 $38,000 $36,900 $38,000 $47,800 $50,000 9 $42,000 $45,500 10 $30,000 $31,000 Pair 11 12 13 14 15 16 17 18 19 20 Female Male $33,000 $35,000 $54,000 $56,000 $36,000 $36,000 $54,000 $53,000 $35,500 $36,000 $42,000 $41,500 $39,000 $38,500 $42,500 $42,000 $31,000 $31,000 $38,000 $39,500 1. Using your calculator or exces, for the sample mean and sample standard deviation, rounded to two decimal places, for both females and males. You may check these values with your instructor before continuing. Each re-attempt will result in a lost point. (4 points) Females: Males: x = XD = x = S = S= and 2. You must find the difference in pay for each pair of employees with a male). For example, the first female value is 44000 and the difference is: 43800-44000 = -200. -200 is the data value you are using. Find the mean of the differences and rounded to two decimal places.
