The purpose of a gauge capability study is to describe the variability of a gauge in repeating its measurement (i.e., does the gauge produce the same result when measuring the same objective?). A gauge capability study was performed on a scale by repeating measurements of the weight of one sheet of paper. Provide a 99% confidence interval for the standard deviation of weight for the following weight data. 3.481 3.448 3.485 3.475 3.472 3.477 3.472 3.464 3.472 3.470 3.470 3.470...
Please use the accompanying Excel data set or accompanying Text file data set when completing the following exercise. An article in Technometrics (1999, Vol. 41, pp. 202-211) studied the capability of a gauge by measuring the weight of paper. The data for repeated measurements of one sheet of paper are in the following table. Construct a 90% one-sided, upper confidence interval for the standard deviation of these measurements. Assume population is approximately normally distributed. Round your answer to 3 decimal...
