a) True b) False 24. Upper and lower control limits are usually set at  6 standard deviations from the mean. a) True b) False The following problems are worth ten (10) points each. 1. A firm produces 1500 units per day using four workers on a five-hour shift. On average, 12% of the units produced are defective and must be scrapped. What is the labor productivity for non-defective units? P = O/I = [1500-(.12*1500)]/4*5 = [1500-180]/20 = 1320/20 = 66 units/hour 2. Birdie Par owns a company that makes golf gloves. She is thinking about introducing a new glove, which would require an additional fixed cost of $20,000 per year. The variable costs for the new glove have been estimated to be $5 per glove. a) If she sells the new glove for $15, how many must she sell to break even? QBE = FC/SP-VC = $20,000/$15-$5 = $20,000/$10 = 2,000 gloves b) If she sells 3,000 gloves at the $15 price, what will the contribution to profit be? Profit = Revenue – Cost = 3,000*$15-[$20,000+(3,000*$5)=$45,000-[$20,000+$15,000] = $45,000-$35,000 = $10,000 3. Insourcing incurs a fixed cost of $1000 and a $5 variable cost. Outsourcing incurs a fixed cost of $2000 and a $2 variable cost. What is the indifference point? Qind = FCmake-FCbuy/VCbuy-VCmake = $1000-$2000/$2-$5 = -$1000/-$3 = ~333 units
