1 Standard deviation is a measure of an instrument's: Accuracy O Range O Static sensitivity O Precision 1 pts 1 pts Question 2 You are using a laboratory balance with a resolution of 2 g to perform quality control on a packaging line. A work colleague takes 10 samples each from two different packaging machines that weight out and package consistent weights of your product. You colleague finds the mean weight of the sampled packages from machine A is 1.25 g higher than the mean weight of the sampled packages from machine B. Your colleague suggests that you should immediately stop production and take apart the packaging machines to find out why the packaged weights from the two machines are different. Do you agree or disagree with your colleague? Pick the best answer below. O Disagree. The difference between the two instruments is less than the resolution of the instruments, so the discrepancy cannot be attributed to anything other than random variation. Agree. The difference between the two instruments is more than 1 standard deviation. O Disagree. The difference between the two instruments is a bias error between the two instruments. O Agree. The difference between the two instruments is statistically significant
