B)the null hypothesis was rejected.
C)there is a statistically significant relationship at the .05 level.
D)the null hypothesis was rejected, and there is a statistically significant relationship at the .05 level.
E)the null hypothesis was rejected, there is a statistically significant relationship at the .05 level, and it is improbable that the observed relationship could have resulted from sampling error alone.

The calculated chi-square value (83.26) is much higher than the critical value (16.91) at the .05 level, leading to the rejection of the null hypothesis, indicating a statistically significant relationship, and suggesting that the observed relationship is unlikely due to sampling error alone.
