The table below shows whether a random collection of people will respond to a survey or not, in different age groups. Test the claim that cooperation of a subject and the age of a subject are independent. χ2R = 15.086

Age	18-21	22-29	30-39	40-49	50-59	60 and over
responded	73	255	245	136	138	202
refused	11	20	33	16	27	49

Critical Values: z0.005 = 2.575, z0.01 = 2.325, z0.025 = 1.96, z0.05 = 1.645

When d.f.=6: t0.005 = 3.707, t0.01 = 3.143, t0.025 = 2.447, t0.05 = 1.943

When d.f.=9: t0.005 = 3.250, t0.01 = 2.821, t0.025 = 2.262, t0.05 = 1.833

When d.f.=44: t0.005 = 2.690, t0.01 = 2.412, t0.025 = 2.014, t0.05 = 1.679

When d.f.=100: t0.005 = 2.625, t0.01 = 2.364, t0.025 = 1.984, t0.05 = 1.660
