FREE-RESPONSE ANSWER
10 Total Points Possible
(a) Maximum 3 points total, 1 point maximum for each correct answer. Must
show work.
(i) The number of emigrants between 1860 and 1870. (1 point maximum)
N 1870 = (N 1860 + B + I) – (D + E) where 1,450 = (3,000 + 30 + 500) – (40 +
E)
E = 2,040
(ii) The number of births between 1870 and 1880. (1 point maximum) N 1880 =
(N 1870 + B + I) – (D + E) 620 = (1,450 + B + 10) – (7 + 1,000)
B = 167
(iii) The population in 1890. (1 point maximum)
N 1890 = (N 1880 + B + I) – (D + E) N 1890 = (620 + 0 + 0) – (2 + 200)
N 1890 = 418
(b) Maximum 3 points total.
Plot the crude birth rate and the crude death rate for Barronsville between
1850 and 1859. Clearly label the axes and the curves. (1 point maximum for
correctly scaling and labeling the axes. Each axis must include all data
between 1850 and 1859. 2 points for correctly plotting both rates.)
