Textbook Question
Chapter 14.1, Problem 14.12ACI
GDP personal consumption expenditures (cont’d). Refer to Exercise 14.11. Suppose the output quantities in 1970, measured in billions of units purchased, are as follows:
Durable goods: 10.9
Nondurable goods: 14.02
Services: 42.6
a. Use the outputs to calculate the Laspeyres index from 1960 to 2015 (same increments as in Exercise 14.11) with 1970 as the base period.
b. Plot the simple composite index of Exercise 14.11 and the Laspeyres index of part a on the same graph. Comment on the differences between the two indexes.

The frozen remains of a young Incan womanwere discovered by archeologist Johan Reinhard on Mt. Ampatoin Peru during an expedition in 1995.a. How much of the original carbon-14 was present if the estimated age of the “Ice Maiden” was 500 years?b. If a 1% error can occur in the carbon-14 measurement, whatis the oldest possible age for the Ice Maiden?
Metropolitan Hospital has estimated its average monthly bed needs, N, as:
N=460+9X�=460+9�
where X = time period (months); (January 2002 = 0)
Assume that no new hospital additions are expected in the area in the foreseeable future. The following monthly seasonal adjustment factors have been estimated, using data from the past five years:
Forecast Metropolitan's bed demand for January, April, July, November, and December 2007.
