Problem 1: A research firm surveyed retired senior executives who had returned to work. They found that after returning to work, 40% were employed by another organization, 25% were self-employed, 25% were either freelancing or consulting, and 10% had formed their own companies. To see if these percentages are consistent with those of Allegheny County residents, a local researcher surveyed 300 retired executives who had returned to work and found that 122 were working for another company, 85 were self-employed, 76 were either freelancing or consulting, and 17 had formed their own companies. At α = 0.10, test the claim that the percentages are the same for those people in Allegheny County.
