To determine which classification of the study is significant, we need to conduct a chi-square test.

Using a chi-square calculator, we can find that the chi-square value for this data is 10.8, with 3 degrees of freedom.

Comparing this value to a chi-square distribution table, we can see that the only classification that is significant at the 0.05 level is D, with a critical value of 7.82. Therefore, we reject the null hypothesis and conclude that classification D is significantly different from the expected frequency of 10 in each cell.
