A researcher wanted to determine whether pedestrian deaths were uniformly distributed over the days of the week. She randomly selected 300 pedestrian deaths, recorded the day of the week on which the death occurred, and obtained the following results (the data are based on information obtained from the Insurance Institute for Highway Safety).

Test the belief that the day of the week on which a fatality happens involving a pedestrian occurs with equal frequency at the α = 0.05 level of significance.
