Consider a chi-square distributed random variable with 12 degrees of freedom and a significance level of 0.025.The chi-square value from the table is 23.337.Which of the following computed values of the chi-square test statistic would lead us to a decision "fail to reject" the null hypothesis?
A)41.47
B)17.12
C)32.59
D)26.43

Since the table value of chi-square is 23.337 at a significance level of 0.025 and with 12 degrees of freedom, any computed chi-square value less than the table value would lead us to fail to reject the null hypothesis. The only computed value less than the table value is 17.12, so the answer is B.
