Find the value of the chi-square test statistic for the goodness-of-fit test. According to recent research, the distribution of the number of children per family in the U.S. is shown in the first accompanying table. A random sample of 700 families with both parents under 40 yielded the data in the second accompanying table. You wish to test the claim that the distribution of the number of children per family for families with both parents under 40 is the same as that of the U.S. as a whole. What is the value of the x² test statistic? Note that the expected frequencies are as follows: more than 3 children: 142.1; 3 children: 149.1; 2 children: 101.5; one child: 112.7; 0 children: 194.6.
