You cut 5 pieces of string having these lengths in inches: 2.9 9.5 5.7 4.2 7.6 A subject measures each length by eye. Make up a set of results from this activity that matches each of the descriptions below. For simplicity, assume that bias means the same xed error every time rather than an \"on the average\" error in many measurements. (a) The subject has a bias of 0.5 inch too long and is perfectly reliable. (b) The subject has no bias but is not perfectly reliable, so that the average difference in repeated measurements is 0.5 inch. (c) A subject measures the first length (true length = 2.9 inches) four times by eye. His measurements are 3.0 2.9 3.1 3.0 What are the four random errors for his measurements? 8.23 Measuring crime. Twice each year, the National Crime Victimization Survey asks a random sample of about 40,000 households whether they have been victims of crime and, if so, the details. In all, nearly 135,000 people answer these questions per year. If other people in a household are in the room while one person is answering questions, the measurement of, for example, rape and other sexual assaults could be seriously biased. Why? Would the presence of other people lead to overreporting or underreporting of sexual assaults? 8.24 Measuring pulse rate. You want to measure your resting pulse rate. You might count the number of beats in 5 seconds and multiply by 12 to get beats per minute. Why is this method less reliable than actually measuring the number of beats in a minute
