Question: From Exercises 12 97 and 12 98 we conjecture that for a
From Exercises 12.97 and 12.98, we conjecture that, for a comparison of two population proportions, the value of the χ2-statistic of a chi-square homogeneity test equals the square of the value of the z-statistic of a two-proportions z-test. Establish that fact.
