Problem 12BSC

Determining Normality. In Exercises 9–12, refer to the indicated sample data and determine whether they appear to be from a population with a normal distribution. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is roughly bell-­shaped.

Secondhand Smoke The cotinine measurements of nonsmokers who were exposed to tobacco smoke at home or work, as listed in Data Set 9 in Appendix B.

From the graph, we see that the data does not appear to be from a population with a normal distribution. If the histogram is roughly bell shaped, then the distribution is approximately normal.
