TRUE OR FALSE? 1. The degrees of freedom for a chi-square test on a two-way table with 2 columns and 5 rows is 4. 2. When comparing several populations, the null hypothesis for the chi-square test becomes: 'The distribution of the response variable is the same in all populations tested.' 3. When using a two-way table to test independence, all data is collected from a single population. 4. The χ2 test establishes the cause of observed associations. 5. A meta-analysis is a pilot study used to determine the feasibility of a proposed experimental design. 6. In a 2 x 2 table, the chi-square test always tests the two-sided alternative. 7. Chi-square tests are often preferable to two sample z tests because they can test either one-sided or two-sided alternatives. 8. If H0 is false, the chi-square statistic has approximately a χ2 distribution with (r-1)(c-1) degrees of freedom.
