In the twentieth century, it was a common practice in Southern California for houses to be built with pools in the backyard. For new homes, however, that practice may be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 158 houses built in Southern California in the twentieth century and an independent, random sample of 83 new houses built in Southern California. The sample of twentieth century houses contained 82 houses with pools, and the sample of new houses contained 27 houses with pools. Based on this survey, can we conclude, at the 0.01 level of significance, that the proportion P, of all Southern California twentieth century houses that were built with pools is greater than the proportion P₂ of all new Southern California houses that were built with pools?
