Step-by-Step Solution:
Step 1 of 3

Solution 1RE Step1: From the above given problem we have lists auto fatalities by day of the week for a recent year (based on data from the Federal Highway Administration). Minitab results are also shown. Use a 0.01 significance level to test the claim that auto fatalities occur on the different days of the week with the same frequency. With = 0.01 level of significance Step2: Our aim is to find provide an explanation for the results. For that consider the null and alternative hypothesis H : The auto fatalities does not occur on the different days of the week with same frequency. 0 H 1 The auto fatalities occur on the different days of the week with same frequency. With = 0.01 level of significance Step3: From the above given MINITAB we can notice that the p(p = 0.000) is less than level of significance hence, we reject null hypothesis with 0.01 level of significance and conclude that auto fatalities occur on the different days of the week with same frequency. The occurrence of more fatalities on weekends can be attributed to the drinking habits during weekends, resulting in poor driving and fatalities.
