Textbook Question
Chapter 15, Problem 34CP
Multiple choice Nonparametric statistical methods are used
- a. Whenever the response variable is known to have a
normal distribution . - b. Whenever the assumptions for a parametric method are not perfectly satisfied.
- c. When the data are ranks for the subjects rather than quantitative measurements or when it’s inappropriate to assume normality and the ordinary statistical method is not robust when the normal assumption is violated.
- d. Whenever we want to compare two methods for getting a good tan.

3) Researchers at Florida State University's Department of Community Medicine in conjunction with the Department of Public Transportation examined the association between alcohol consumption and the time it took to respond to a signal. Their data revealed that subjects who drank more alcohol took longer to respond to signals than subjects who drank no alcohol. These data are evidence_____________________________________.
