Compute the expected counts for each day of the week. 

A researcher wanted to determine whether certain accidents were uniformly distributed over the days of the week. The data show the day of the week for n = 304 randomly selected accidents. Is there reason to believe that the accidents occur with equal frequency with respect to the day of the week at the a= 0.05 level of significance? Click the icon to view the table. Click here to view the Chi-Square distribution table. H₁: More accidents occur earlier in the week than later. Compute the expected counts for each day of the week. Day of the Week Observed Count Sunday Monday Tuesday Wednesday Thursday Friday Saturday 40 40 27 42 42 51 62 Expected Count C (Round to three decimal places as needed.)
