    Question

    In a research study about the association between educational program and civil engagement, 100 psychology students and 50 mathematics students were surveyed and asked whether they were considering to engage in volunteer activities during their program. The choices available to each person were “Yes,” “No,” and “Undecided.” Listed below are the results of the survey. Determine the Chi-square test statistic to test independence and the corresponding degrees of freedom.


    1. FALSE: χ2=1.73\chi^{2} = 1.73, with 6 degrees of freedom.
    2. FALSE: χ2=7.69\chi^{2} = 7.69, with 6 degrees of freedom.
    3. FALSE: χ2=1.73\chi^{2} = 1.73, with 2 degrees of freedom.
    4. TRUE: χ2=7.69\chi^{2} = 7.69, with 2 degrees of freedom.
