Female Arm Circumferences A sample of arm circumferences (cm) of females from Data Set 1 “Body Data” in Appendix B: 40.7, 44.3, 34.2, 32.5, 38.5. Constructing Normal Quantile Plots. In Exercises 17 and 18, use the given data values to identify the corresponding z scores that are used for a normal quantile plot; then identify the coordinates of each point in the normal quantile plot. Construct the normal quantile plot, then determine whether the sample data appear to be from a population with a normal distribution.
