In a recent year, the Better Business Bureau settled 75% of complaints they received. You have been hired bythe Bureau to investigate complaints this year involving computer stores. You plan to select a random sampleof complaints to estimate the proportion of complaints the Bureau is able to settle. Suppose your sample sizeis 134. What is the probability that the sample proportion will be at most 3 percent more than the populationproportion?(Enter your answer as a number accurate to 4 decimal places.)

Ty In the t eth 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 be changing, possibly as a measure to help reduce climate change. A recent study examined a random sample of 164 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 56 houses with pools, and the sample of new houses contained 26 houses with pools. Based on this survey, can we conclude, at the 0.10 level of significance, that the proportion p₁ of all Southern California twentieth century houses that were built with pools is greater than the proportion p, of all new Southern California houses that were built with pools?
