Concerning the relationship between the Chi-Squared Test and Two Proportion Z Test with two-sided alternative hypothesis, which of the following statements is true? The Chi-Squared and Two Proportion Z with two-sided alternative hypothesis Tests are used only for sample sizes smaller than 10. The Chi-Squared test statistic is equal to the test statistic for Two Proportion Z Tests. The Goodness of Fit 2x2 produces the same results as the Two Proportion Z Test with two-sided alternative hypothesis. The Chi-Squared Test for Homogeneity 2x2 produces the same p-value as the Proportion Z Test with two-sided alternative hypothesis.

Concerning the relationship between the Chi-Squared Test and Two Proportion Z Test with two-sided hypothesis, which of the following statements is true? The p-value from the two tests are the same. The degrees of freedom of the Chi-Square Test is equal to 1.5 times the sample size of the Two Proportion Z Test. The p-value from the two tests are not the same.

Extending the Concepts and Skills Chi-Square Homogeneity Test and Two-Proportions z-Test. As we mentioned on page $619,$ the chi-square homogeneity test for comparing two population proportions and the two-tailed two-proportions $z$ -test are equivalent; that is, they always yield the same result. In the following exercises, you are to establish that fact. From Exercises 13.97 and $13.98,$ we conjecture that, for a comparison of two population proportions, the value of the $x^{2}$ -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.
