A survey was done among retired senior executives who had returned to work. It found that after returning to work, 36% were employed by another organization, 31% were self-employed, 26% were either freelancing or consulting, and 7% had formed their own company. To see if these percentages are consistent with residents of a county, a local researcher surveyed 300 retired executives who have returned to work and found that 102 were working for another company, 87 were self-employed, 96 were either freelancing or consulting, and 15 have formed their own companies. At = 0.1, test the claim that the percentages are the same for those people in that county. Is there enough evidence to reject the claim?
