In a study of 90 patients on renal dialysis, Farhad Atassi (A-7) assessed oral home care practices. He collected data from 30 subjects who were in (1) dialysis for less than 1 year, (2) dialysis for 1 to 3 years, and (3) dialysis for more than 3 years. The following table shows plaque index scores for these subjects. A higher score indicates a greater amount of plaque. At the 5% level of significance test the claim that the plaque index scores differ between these groups.
