Modeling labor force data. In Exercise 35 from Section 7.2,
we modeled the size of the U.S. labor force with the equation
a. Add a line to the table that you began in Exercise 35 from
Section 7.2 as follows:
2003 (year 0) | 2004 (year 1) | 2005 (year 2) | 2006 (year 3) | 2009 (year 6) | |
Actual Data | 146 | 147 | 149.2 | 151.3 | 154.1 |
Values predicted by your model | 146 | 147.77 | 149.54 | 151.31 | 156.62 |
Values predicted by the line of best fit | 145.66 | 147.47 | 149.28 | 151.09 | 156.52 |
Values predicted by parabola of best fit | 145.935 |
b. Does the line of best fit or the parabola of best fit seem to model the data better? Explain your answer.

- TEST FOR UNDERSTANDING FOR EXAMPLE 5.16 In the study Economics of Scale in High School Operation by J. Riew, the author studied data from the early 1960s on expenditures for high schools ranging from 150 to 2400 enrollment. The data he observed were similar to those in the table below. n=enrollment 200 600 1000 1400 1800 C=costperstudent,indollars 667.4 545.0 461.0 415.4 408.2 Model these data using a quadratic function. Round regression parameters to four decimal places. According to this model, what enrollment produces the minimum cost per student?arrow_forwardCellular Phone Subscribers The table shows the numbers of cellular phone subscribers y in millions in the United States from 2008 through 2013.

Let x represent the year, with x=8 corresponding to 2008. (b) Use the linear regression capabilities of a graphing utility to find a linear model for the data. How does this model compare with the model obtained in part a? (c) Use the linear model to create a table of estimated values for y. Compare the estimated values with the actual data.arrow_forwardHOW DO YOU SEE IT? Discuss how well a linear model approximates the data shown in each scatter plot.arrow_forward
