Q. U.S. Census Bureau estimates of the average number of persons per household in the United States for census years between 1850 and 2000 are shown in the following table. Year Per House 1850 5.55 1860 5.28 1870 5.09 1880 5.04 1890 4.93 1900 4.76 1910 4.54 1920 4.34 1930 4.11 1940 3.67 1950 3.37 1960 3.35 1970 3.14 1980 2.76 1990 2.63 2000 2.59 (a) Determine the least squares line for these data. Use the equation of this line to estimate the number of persons per household in the year 2011. (b) What is the slope of the line? (c) Based on the regression line, what would be the predicted persons per household in the year 2300? (d) What is the lowest possible value of… [cont.]

A. (a) The least squares regression line is y = 44.392 - 0.0209x where x is the year and the estimate for 2011 would be 2.36 persons. (b) The slope is therefore -0.0209 persons per year. That means the average occupancy is falling by about one person every 50 years. (c) For x = 2300, y = -3.7, which is clearly nonsense. (d) The minimum occupancy could be zero, if everyone was a vagrant and no one ever lived at an address; or 1.0 if everyone has to be listed as living somewhere ! The problem with this analysis arises from the assumption that the relationship is a straight line. Obviously it's not.

A. a) P(1910) = 76 e^10k = 92 k = ln (92/76)/10 So P(2000) = 76 e^100 ln (92/76)/10 = 513.5 b) P(1990) = 227 e^10k = 250 k = ln (250/227)/10 So P(2000) = 227 e^20 ln (250/227)/10 = 275.3

A. don't see why this is a calc problem Oo. Exponential model is A = Pe^(rt) P is how much you start with. A is howmuch you end up with. and t is the amount of time passed. So from 1900 to 1910, the amount of time passed is 10 years, and 76 is how much you start with (P) 92 is how much you end with (A) so you have 92 = 76*e^(r*10) Solve this for r. (I'm too lazy.) and then replace that value of r into your equation. Now you have the power to predict what the population will be in 2000. Just use the started population in 1910 as you (A) and leave P as your variable. Use t = 90, (90 years from 1910 to 2000) and the rate you found in the first problem. The only variable you should have left is P, which is your prediction… [cont.]

A. A. The increase of population from1900 to 1910 was 16 mil which is 21.05% increase. Using that as the percentage in the formula, and 76 as the initial population, the equation is: 76 e^.2105t where t is the number of decades past 1900. The discrepency could be a larger percentage increase between 1900 and 1910 than other decades. B. Using 1970 and 1980 gives a different percentage of increase at 11.82%. The equation now changes to: 203 e^.1182t with t = # of decades so the population prediction is 289.4 mil in 2000 and 325.7 mil. in 2010

The vast majority of these immigrants come from minority white countries in East and West Africa (e.g. Kenya and Nigeria). While less than 2 percent originate from North or South Africa (CIA World Factbook, 2004; Yearbook of immigration Statistics, 2003). In an analysis of Census Bureau data by the Journal of Blacks in higher education, African immigrants to the United States were found more likely to be college educated than any other immigrant group, which included those from Europe, North America and Asia (see also Nisbett, 2002; U.S. Bureau of the Census,… [cont.]
