Draw a scatter diagram for these data: Would you be justified in using the techniques of linear regression on these data to find the line of best fit? Explain. The values of x used to find points for graphing the line yˆ = 14.9 + 0.66x in Figure 3.24 (p. 149) are arbitrary. Suppose you choose to use x = 20 and x = 50 a. What are the corresponding values? b. Locate these two points ...For Example 3.7 (p. 150) and the scatter diagram in Figure 3.26 on page 151: a. Explain how the slope of 4.71 can be seen. b. Explain why the y-intercept of-186.5 cannot be seen. Consider the College Women’s data presented in Example 3.7 and the line of best fit. When estimating the line of best fit from a scatter diagram, the choice for the two points (x1, y1) and (x2, y2) to be used is somewhat ...The graph on page 162 shows the relationship between three variables: number of licensed drivers, number of registered vehicles, and the size of the resident population in the United States from 1960 to 2007.
