65) The Quality Assurance Department selected 12 samples of 100 printed circuit boards and tested them. The number of defective printed circuit boards in each sample was 3, 3, 0, 5, 1, 1, 5, 6, 6, 2, 0, and 1. The measurement of quality is based on A) an attribute B) a variable C) a scale D) a chart 66) A new machine is set or calibrated to fill tubes of toothpaste at precisely 6.75 ounces. Then, once the machine is running, a sample of six tubes is taken every three hours and weighed with the following results: WEIGHT OF TOOTHPASTE Time 7 am 6.69 6.68 6.79 6.77 6.74 6.76 10 am 6.71 6.72 6.71 6.76 6.75 6.74 1 pm 6.66 6.68 6.67 6.71 6.76 6.78 4 pm 6.73 6.74 6.72 5.76 6.78 5.75 7 pm 6.75 6.73 6.75 6.77 6.79 6.75 The measurement of quality is based on A) an attribute B) a variable C) a scale D) a chart 67) Random samples of four items are selected from a manufacturing process at regular intervals and a certain quality characteristic is measured. After 25 samples, EX = 15,350 and ER = 411.4 The measurement of quality is based on A) an attribute B) a variable C) a scale D) a chart 68) A quality control chart is used to monitor the customer wait time at a local call center. Sample means of five times are averaged and plotted over time. Over the last hundred sample means, one sample mean was outside a control limit. The process is A) out of control B) in control C) highly variable D) showing an assignable cause
