This question i am doing most of part, also I atteched the graph image, I need help only Question No 2). a, Question and 3). part C, D and E, please help within two hours, please plese 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. (Data from Wikipedia.org/wiki/mile_run_world_record_progression)    Year Men's Times Times in Seconds Athlete's Nationality 1965 3:53.6   France 1966 3:51.3   US 1967 3:51.1   US 1975 3:51.0   Tanzania 1975 3:49.4   New Zealand 1979 3:49.0   UK 1980 3:48.8   UK 1981 3:48.53   UK 1981 3:48.40   UK 1981 3:47.33   UK 1985 3:46.32   UK 1993 3:44.39   Algeria 1999 3:43.13   Morocco     Year Women's Times Times in Seconds Athlete's Nationality 1967 4:37.0   UK 1969 4:36.8   Netherlands 1971 4:35.3   West Germany 1973 4:29.5   Italy 1977 4:23.8   Romania 1979 4:22.09   Romania 1980 4:21.68   US 1981 4:20.89   Soviet Union 1982 4:18.08   US 1982 4:17.44   Romania 1985 4:16.71   US 1989 4:15.61   Romania 1996 4:12.56   Russia   The purpose of this project is for you to apply concepts we have discussed in class, such as modeling with the TI-83/84 calculator, drawing scatter plots, making predictions, and solving systems of linear equations. The process you are to use is outlined below. Once you have completed the project, you should upload a neatly written PDF summary of your results using the Assignments tool in Sakai. Each question should be numbered as shown below, with all graphs, math work, and explanations shown clearly. You may work with other students in the class and discuss your findings.   Using the Desmos graphing calculator or graph paper (which may be printed from an online image), complete the following steps:   Visualize the data   Use the horizontal axis (x) to represent the year. Begin with year 1960 and continue through year 2050. Choose an appropriate scale for the x-axis to model the data.   Convert all the times to unrounded seconds instead of minutes and seconds; list these times in the table under “Times in Seconds.”   Use the vertical axis (y) to represent the times, in seconds. Begin with 200 seconds and continue to 300 seconds. Choose an appropriate scale for the y-axis to model the data.   Use an “x” 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.   e) Title your graph and label the x and y Insert your graph below.           Find the models   Using the years as x and the times in seconds for men as y, enter the mens’ data in your calculator in L1 and L2, respectively. Do the same for women, except use L3 and L4 . Set up the plots in your calculator to display L1 and L2 as Plot1. Set up Plot2 to display L3 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 and insert a picture of your calculator graph below. It should resemble the one you created by hand.       Using the Calculate menu under Stats, find a linear regression model for L1 and L2. Write the corresponding equation, rounding to three decimal places for a and b.       Using the Calculate menu under Stats, find a linear regression model for L3 and L4. Note that the format will be LinReg (y=ax+b) (L3,L4). Write the corresponding equation, rounding to three decimal places for a and b.       d) Draw the two lines whose equations you found in parts b) and c) on the graph you produced in part 1. Where do the lines appear to intersect? Give approximate coordinates, based on the grid, as integers.   Question 3. c) Use your models to predict the world record times for men and women in 2020, 2050, and 2270. Give your answer for each year in minutes and seconds, rounded to the nearest second. Are the predictions reasonable? Why or why not?       d) Find and interpret the slopes of both regression lines. (What does the       slope of each equation mean in the context of the given data?) Based on       the slopes, whose times are improving more as the years go by, men’s’ or women’s’?       e). Find and interpret the y-intercepts of the models. Do the y-intercepts give any meaningful information? Why or why not?
