The U.S. Census Bureau computed the proportion of U.S. residents who lived in each of the four geographic regions in the year 2000. There were 19% in the Northeast, 22.9% in the Midwest, 35.6% in the South and 22.5% in the West. Then a simple random sample was drawn of people living in the U.S. in 2011. Can you conclude the distribution in where people live in the U.S. has changed from 2000 to 2011? Use a 5% significance to decide. Round to the fourth as needed.

Are American men or women more into online dating? Researchers from a pop culture magazine conducted a study to see if there is a difference in the proportion of men and women under 30 that use online dating sites. They collected independent random samples of 96 women and 88 men, ranging from 18-30 years old, from across the US. Of the women, 67 reported using online dating sites, while 62 of the men reported using online dating sites. Assume the subjects responded honestly. What would be the test statistic and P-value for performing a hypothesis test Ho : P1 = P2 vs. HA : P1 + P2 ?

Thirty-two percent of all Americans drink bottled water more than once a week (Natural resources Defense Council, December 4, 2015). Suppose you have been hired by the Natural Resources Defense Council to investigate bottled water consumption in St. Paul. You plan to select a sample of St. Paulites to estimate the proportion who drink bottled water more than once a week. Assume the population proportion of St. Paulites who drink bottled water more than once a week is 0.32, the same as the overall proportion of Americans who drink bottled water more than once a week. E(p bar) = Based upon a sample of 540 St. Paulites, what is the probability that the sample proportion will be within 0.08 of the population proportion (to 4 decimals). Probability = Suppose you select a sample of 230 St. Paulites. Show the sampling distribution of p bar (to 4 decimals).

A real estate agency, located in a metropolitan area in the northeastern U.S., kept data on the various types of properties purchased in the area. Historically, 15% of purchases were for condominiums, 30% were for townhouses, 40% for single family homes, 10% for commercial properties and 5% for land. With changing demographics, the agency wondered if the current distribution matches the historical distribution. Recent data showed the following: Type of Property Condos Townhouses Homes Commercial Land Frequency 89 121 78 25 12 Based on the historical distribution, we would expect how many homes to be purchased?
