3) An analysis of automobile accidents was conducted to see whether large automobiles are safer than smaller ones. The data for 100 accidents are as follows: Non-Fatal Fatal Small 10 20 30 Size of automobile Medium 20 10 30 Large 30 10 40 3a) Conduct a chi-square (x²) test to determine whether smaller-sized cares are more likely to be involved in fatal accidents (show work on this page). What conclusion can you draw from this chi- square test? 60 40 100
