The top executives of Company X would like to reduce the blood pressure of hapless employees. They came up with a miracle drug call MiracleOww. Unfortunately, there may be a side effect, abnormal anxiety, associated with the miracle drug. When they carried out a clinical test of the miracle drug, employees were randomly divided into three groups. Group 1 received MiracleOww, Group 2 received a placebo, and Group 3 receives Mavik, a new blood pressure reducing drug currently available. The clinical results are summarized in the following table.

Is there evidence to indicate that the proportion of employees in each group who experienced abnormal anxiety is different at 0.01 significance level?
