Each respondent in the Current Population Survey of March 2005 was classified as employed, unemployed, or outside the labor force. The results for men inCalifornia age 35-44 can be cross-tabulated by marital status, as follows:
Employed:790 (Married),98 (Widowed, divorced or separated),209 (Never married)
Unemployed: 56 (Married),11 (Widowed, divorced or separated),27 (Never married)
Not in labor force: 21 (Married),7 (Widowed, divorced or separated), 13 (Never married)
Men of different martial status seem to have different distributions of labor force status. Or is this just chance variation? (You may assume the data came from asimple random sample.)

Johanna and Jake Berkvom own Campus Fashions. From its inception Campus Fashions has sold goods on either a cash or credit basis, but no credit cards have been accepted. During the past several months, the Berkvoms have begun to question their credit sales policies. First, they have lost some sales because of their refusal to accept credit cards. Second, representatives of two banks have convinced them to accept their credit cards. One bank, City Bank, has stated that (1) its credit card fee is 4% and (2) it pays the retailer 96 cents on each $1 of sales within 3 days of receiving the credit card billings. The Berkvoms decide that they should determine the cost of carrying their own credit sales. From the accounting records of the past 3 years they accumulate these data: 2015 2014 2013 Net credit sales $600 000 $720 000 $480 000 Collection agency fees for slowpaying customers 2 940 3 000 1 920 Wages of part-time accounts receivable clerk 4 560 4 560 4 560 Credit and collection expenses as a percentage of net credit sales are as follows: uncollectable accounts 1.6%, invoicing and mailing costs 0.5%, and creditinvestigation fee on new customers 0.15%. Johanna and Jake also determine that the average accounts receivable balance outstanding during the year is 5% of net credit sales. The Berkvoms estimate that they could earn an average of 10% annually on cash invested in other business opportunities. Required Answer the following: (a) Present calculations for each year showing total credit and collection expenses in dollars and as a percentage of net credit sales. (b) Determine the net credit and collection expenses in dollars and as a percentage of sales after considering the revenue not earned from other investment opportunities. (Note: The interest revenue lost on the cash held by the bank for 3 days is considered to be immaterial.) (c) Discuss both the financial and non-financial factors that are relevant to the decision.
