The chi-square distribution is continuous, whereas the test statistic used in this section is discrete. Some statisticians use Yates' correction for continuity in cells with an expected frequency of less than 10 or in all cells of a contingency table with two rows and two columns. With Yates' correction, we replace

Given the contingency table in Exercise 10, find the value of the x1 test statistic with and without Yates' correction. In general, what effect does Yates' correction have on the value of the test statistic?
