Mother and Daughter Heights The graph shows the heights of mothers and daughters. (Source: StatCrunch: Mother and Daughter Heights.xls. Owner: craig_slinkman)
a. As the data are graphed, which is the independent variable and which the dependent variable?
b. From the graph, approximate the predicted height of the daughter of a mother who is 60 inches (5 feet) tall.
c. From the equation, determine the predicted height of the daughter of a mother who is 60 inches tall.
d. Interpret the slope.
e. What other factors besides mother’s height might influence the daughter’s height?

- The graph shows the number of students enrolled in public colleges for selected years (Source: U.S. National Center for Education Statistics, www.nces.ed.gov). The x variable represents the number of years since 1990 and the y variable represents the number of students (in millions). a. Use the points (4, 11.2) and (14, 13.0) to write a linear model for these data. 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. In the event that the linear trend continues beyond the last observed data point, use the model in part (a) to predict the number of students enrolled in public colleges for the year 2020.
