Demographic study was conducted to verify the age distribution among residents in suburban areas. There were k = 6 age groups selected for this study. The observed frequencies and theoretical proportions under the null hypothesis are shown in the table below

Age group	Under 20	20, 30	30, 40	40, 50	50, 65	65 and above	total
Frequency	132	148	224	62	188	46	800
Proportions	.15	.20	.25	.1	.25	.05	1
