Just calculate to part c, d and e with detail. 1. Almost all U.S. light-rail systems use electric cars that run on tracks built at streetlevel. The Federal Transit Administration claims light-rail is one of the safest modesof travel, with an accident rate of.99 accidents per million passenger miles ascompared to 2.29 for buses. The following data show the miles of track and theweekday ridership in thousands of passengers for six light-rail systems (USA Today,January 7, 2003).CityMiles of TrackRidership (1000s)Cleveland1715Denver1936Portland4078Sacramento2328San Diego5075San Jose3331St. Lois3742a) Develop a scatter diagram for these data. Does a linear relationship appearreasonable? Explain.b) Develop the least squares estimated regression equation. Include a table likethe one in the Lecture notes 13, Table 14.2.c) Did the estimated regression equation provide a good fit? Explain.d) Develop a 95% confidence interval for the mean weekday ridership for alllight-rail systems with 30 miles of track.e) Suppose that Charlotte is considering construction of a light-rail system with30 miles of track. Develop a 95% prediction interval for the weekdayridership for the Charlotte system. Do you think that the prediction intervalyou developed would be of value to Charlotte planners in anticipating thenumber of weekday riders for their new lightrail system? Explain.
