This is part of a math project I'm doing, and I'm having trouble finding a scale for the graph below. Feel free to look at the rest, though.

MAT 171 Project #1 World Records for the Mile Due Date: Sunday, Oct. 24th The following are 13 world record times for men and women in the mile race as ratified by the International Association of Athletics Federations. The mile is the only non-metric distance that is recognized for record purposes. The times are given in minutes and seconds. Notice times prior to 1981 are accurate to a tenth of a second. Beginning in 1981, IAAF began recognizing times to a hundredth of a second. Also notice that the years of the records are not the same for men and women.

The process you are to use is outlined below. Once you have completed the project, you should turn in a neatly written summary of your results. You will turn in a graph, constructed in parts 1c and 2e, and turn in answers to all remaining parts. Each question should be numbered as shown below, with all work shown. Any questions requiring verbal responses should be answered in complete sentences. You may work with other students in the class and discuss your findings. 1. Visualizing the data. Using graph paper, complete the following steps: a) Use the horizontal axis (x) to represent the year. Begin with year 1960 and continue through year 2050. You will need to choose an appropriate scale for the x-axis to model the data. b) Use the vertical axis (y) to represent the times, in seconds. You will first need to convert all the times to seconds instead of minutes and seconds. Then choose an appropriate scale for the y-axis to model the data, begin with 200 seconds and continue to 300 seconds. c) Use a plus (+) sign to represent the data for men, and plot the points on the grid using the year as the x coordinate and the times for men as the y coordinate. Use an "o" to represent the data for women, and plot the points on the same grid using the year as the x coordinate and the times for women as the y coordinate. d) Title your graph and label the x and y axes. 2. Finding the models a) Using the years as x and the times in seconds for men as y, enter the data in your calculator in L, and Ly, respectively. Do the same for women except use L, and L4 b) Set up the plots in your calculator so that you can display L, and L, as Plot1. Set up Plot2 to display L, and L4 (Recall that the setup for plots is done with 2nd Y=. Make sure that each plot uses a different mark so that you can distinguish between the two.] Use Zoom 9 to view the scatter plot, once you have set up the plots. Then adjust the window to match the grid on your graph paper. It should resemble the one you drew in part I. c) Using the Calculate menu under Stats, find a linear regression model for L, and Ly, Write the corresponding equation, showing accuracy to three decimal places for a and b.
