Motor vehicle accidents are rare events, but it is always better to have fewer. vehicle speed may be related to the number of accidents, and in general it is believed that slower speeds will lead to fewer accidents. on a stretch of highway 42, the average number of accidents per day was 0.23. a month ago, the speed limit was changed from 60 miles per hour to 50 miles per hour. in the one-month period following the change in the speed limit, three accidents were observed. explain in detail how you would test whether this is a significant decrease (3pts). include a description of your null and alternative hypotheses.
