For several decades, it was a common practice in Southern California for houses to be built with pools in the backyard (as any airplane flight which ends at a Southern California airport will reveal). Now, however, that practice may be changing, possibly because of the recent demand for landscaped homes, which experts believe help reduce pollution. A recent study examined a random sample of 175 houses built in Southern Californa between 1950 and 1985 and an independent, random sample of 66 houses built in Southern California from 1992 to the present. The sample of houses built in 1950-1985 contained 84 houses with pools, and the sample of houses built from 1992-present contained 20 houses with pools. Based on this survey, can we conclude, at the 0.05 level of significance, that the proportion p, of all Southern California houses built in 1950-1985 that were built with pools is greater than the proportion p, of all Southern California houses built from 1992-present that were built with pools? Perform a one-tailed test. Then fill in the table below. Carry your intermediate computations to at least three decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) The null hypothesis: H :0 The alternative hypothesis: H, :0 OSO The type of test statistic: |(Choose one) v The value of the test statistic: (Round to at least three decimal places.) The critical value at the 0.05 level of significance: (Round to at least three decimal places.) Can we condude that the proportion of Southerm California houses built with pools from 1950-1905 greater than the proportion from 1985-present Yes (C No
