You obtain a sample chi-square test statistic of -5.49. On the basis of this value, you know that (CHOOSE ONE) A) the observed frequencies are higher than the expected frequencies across at least half of the categories. B) you have made a calculation error; chi-square values cannot be negative. C) there is a negative association between your two variables. D) the observed frequencies are lower than the expected frequencies across all categories.
