According to information released by the U.S. Census Bureau in July 2009, the population of Tuscaloosa, Alabama in the year 2000 was 77,906. If P(f) is the population of Tuscaloosa t years after 2000, interpret P(8) – P(7) = 2,063. A The product of the population in the year 2000 and 8 minus the product of the population in year 2000 and 7 is 2,063 citizens. 8 The change in the city's population from 2007 to 2008 is 2,063 citizens. C. The product of the population in the years 2000 and 2008 minus the product of the population in the years 2000 and 2007 equals 2,063 citizens. D. None of the above

A study wants to investigate whether eating oat bran lowers the serum cholesterol levels. Fourteen individuals were randomly selected and their serum cholesterol was measured. Then, they were assigned to an oat bran diet for two weeks, and their serum cholesterol was measured at the end of that period. The differences on the serum cholesterol levels before and after the diet can be summarized below: 14 14 D; = 5.08, > (D; – D)² = 2.142, D; = Cholesterol; before - Cholesterol; after, i=1 i=1 where D; is the difference between the cholesterol level before and after the diet. Do these results provide evidence that the diet lowers the cholesterol levels? Use a 0.05 level of significance. Assume that cholesterol levels are normally distributed. Hint: S3 = 2 D.-D)? 14-1

Data collected in the 2010 U.S. census showed that men represent 49.2% of the population and women represent 50.8% of the population. A researcher plans to survey 5 rural hospitals and calculate the difference in sample proportions between male births and female births. At each hospital, the researcher will record the percentage of male births and the percentage of female births. Assume each hospital has about 100 births per year. We define the difference in sample proportions as “male” minus “female.” The standard error is about 0.07. Which sequence of sample differences is the most likely? 0.12, 0, -0.25, -0.08, 0.23 0.017, 0.039, -0.010, -0.081, -0.005 -0.016, -0.016, 0, -0.016, -0.016
