Solution Summary: The author explains how to calculate a linear equation relating y to x by using data points.
Suppose that
y
represents the average consumer spending on television services per year (in dollars), and that
x
represents the number of year since 2004.
a. Use the data points (2,308) and (6,408) to write a linear equation relating
y
to
x
.
b. Interpret the meaning of the slope in the context of this problem.
c. Interpret the meaning of the
y
-intercept
in the context of this problem.
d. Use the model from part (a) to estimate the average consumer spending on television services for the year 2007.
Use the properties of logarithms, given that In(2) = 0.6931 and In(3) = 1.0986, to approximate the logarithm. Use a calculator to confirm your approximations. (Round your answers to four decimal places.)
(a) In(0.75)
(b) In(24)
(c) In(18)
