Question:

14.52 Are You a Good Driver? How would you rate yourself as a driver? According to a survey, most Albertans think they are good drivers but have little respect for others' driving ability. The data show the distribution of opinions according to gender for two different questions, the first rating themselves as drivers and the second rating others as drivers. We assume that there were 100 men and 100 women in the surveyed group. image text in transcribed
