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=314 randomly selectedaccidents. Is there reason to believe that the accident occurs 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.H₁: At least one proportion is different from the others.O D.
