Example 1: An automotive supplier of interior parts places several electrical wires in a harness. A pull test measures the force required to pull spliced wires apart. A customer requires that each wire spliced into the harness must withstand a pull force of 20 pounds. A random sample of 20-gauge wires yielded the following pull force: 28.8 24.4 30.1 25.6 26.4 23.9 22.1 22.5 27.6 28.1 20.8 27.7 24.4 25.1 24.6 26.3 28.2 22.2 26.3 24.4 Total Count Mean StDev Variable pull force 20 25.475 2.494 Find the sample size required to estimate the mean pull force with 99% confidence with a) the margin of error of 1 b) the length of the interval 1
