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.

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.

Q. Generation Y YA users, how much do YOU know about the history of "Asians"? But you don't know about it much. If you are interested, read below and share your thoughts. "The 1960 census racial categories included American Indian, Chinese, Filipino, Hawaiian, Japanese, Negro, part Hawaiian, White, Eskimo and Aleut" "The 1970 census racial categories included: Chinese, Filipino, Hawaiian, Indian American, Japanese, Negro or Black, other, White, Hispanic origin of any race, and White, not of Hispanic origin.

The following are facts about persons defined as "poor" by the Census Bureau, taken from various gov ernment reports: Forty-three percent of all poor households actu ally own their own homes. The average home owned by persons classified as poor by the Census Bureau is a three-bedroom house with one-and-a-half baths, a garage, and a porch or patio.

A. I live in England. I am concidered by the state to be living in poverty. Compare to many in Britain I have very little. Yet I consider myself to be very lucky.
