Textbook Question
Chapter 2.2, Problem 118E
Legalize of Not? The attitudes toward legalization of marijuana changed between 1995 and 2012. The formula A(x) = − 1.6x + 3265 gives the percentage of people in year x who were against legalization, and the formula F(x) = 1.5x − 2968 gives the percentage of people in year x who were in favor of legalization. (Source: Gallup Poll.)
(a) Interpret the slope of the graphs of A and F.
(b) Estimate the year when the percentages for and against were equal.

A researcher finds a correlation (r) of 0.50 between height and weight. what variation in weight can be explained by the variation in height?
A pediatrician wants to determine the relation that exists between a child's height (x) and head
circumference (y). She randomly selects 11 children from her practice and measures their height and head
circumference in inches. She finds that the correlation is 0.694, and the regression equation is
y = 0.294x + 2.02.
What proportion of the variation in head circumference can be explained by the variation in the values of
height? Round your answer to three decimal places.
