Question
Based on the results, does the distribution of fatal injuries for riders not wearing a helmet follow the distribution for all other riders at a significance level of α = 0.05? A. Do not reject Ho. There is sufficient evidence that the distribution of fatal injuries for riders not wearing a helmet follows the distribution for all riders. B. Do not reject Ho. There is not sufficient evidence that the distribution of fatal injuries for riders not wearing a helmet does not follow the distribution for all riders. C. Reject Ho. There is sufficient evidence that the distribution of fatal injuries for riders not wearing a helmet does not follow the distribution for all riders. D. Reject Ho. There is not sufficient evidence that the distribution of fatal injuries for riders not wearing a helmet follows the distribution for all riders. (b) Compare the observed and expected counts for each category. What does this information tell you? O A. Motorcycle fatalities from head injuries occur less frequently for riders not wearing a helmet. B. Motorcycle fatalities from head injuries occur more frequently for riders not wearing a helmet. C. Motorcycle fatalities from thorax injuries occur more frequently for riders not wearing a helmet.
