An obstetrician wants to know whether or not the proportions of children born on each day of the week are the same. She randomly selects 500 birth records and obtains the data shown in table. Is there reason to believe that the day on which a child is born occurs with equal frequency at the alpha= 0.01.

Observed count (O)	46	76	83	81	81	80	53
