B. The critical value is chi²(0.01,7) = 18.4753
C. The decision rule would be to reject h0 and accept h1 if the test statistic is higher than the critical value
D. Test statistic = summation (Oi-Ei)²/E

24.6> 18.4753
F. The inference is that accidents are not evenly distributed at 0.01 level of significance.
