Chapter 10, Problem 64CRE

In exercises $10.57$ to $10.64$, choose an appropriate test from those listed below. Unless otherwise stated, assume large expected counts.

Chi-square test of goodness of fit Chi-square test of independence Chi-square test of homogeneity Fisher’s Exact Test

No test because the data represent a population, not a sample
