# Question

The chi-square test described in this chapter can be used for tables with more than two rows and/ or columns. Use software (such as Excel), a calculator, or a website to find the p-value for each of the following chi-square statistics calculated from a table of the specified number of rows and columns. You may round off your answer to three decimal places. In each case, specify the degrees of freedom you used to find the p-value. (Remember that in general, degrees of freedom for a table with r rows and c columns are df = ( r – 1) ( c – 1).) Then make a conclusion about whether you would reject the null hypothesis for a test with level 0.05.

a. Two rows and three columns; chi-square statistic = 7.4

b. Three rows and three columns; chi-square statistic - 11.15

c. Four rows and three columns; chi-square statistic = 7.88

d. Four rows and two columns; chi-square statistic = 12.20

a. Two rows and three columns; chi-square statistic = 7.4
