reports the results of a survey in which managers were asked which methods played a major role in the risk management strategy of their firms. In a sample of 43 oil companies, 22 indicated that risk transfer played a major role, while in a sample of 93 construction companies, 55 reported that risk transfer played a major role. Can we conclude that the proportion of oil companies that employ the method of risk transfer is less than the proportion of construction companies that do? Use alpha 0.05.
