Chapter 6, Problem 19BSC(choose chapter or problem)
Constructing Normal Quantile Plots. In Exercises 17−20, 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 data appear to be from a population with a normal distribution.
Brain Volumes A sample of human brain volumes ( cm 3 ) is obtained from those listed in Data Set 6 from Appendix B: 1272, 1051, 1079, 1034, 1070, 1173, 1079, 1067.

ANSWER:Problem 19BSC
Answer:
Step1 of 3:
We have A sample of human brain volumes (cm3) is obtained from those listed in Data Set 6: 1272, 1051, 1079, 1034, 1070, 1173, 1079, 1067.
Step2 of 3:
We need 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 data appear to be from a population with a normal distribution.
Step3 of 3:
The given data in Ascending order
