Use the sample data in the accompanying table. The table includes the results for the top performers in the 1996 Molson Indy Toronto. Note that the data in the Final Position column are ordinal and thus should not be used in the regressions. The distance between the first and second final positions, for example, may be quite different from the distance between the second and third final positions. Intervals between starting positions, however, are assumed to correspond to consistent track distances. Times are given in seconds and speeds in miles per hour.

Use only the paired data for starting position and qualifying speed. For a driver whose qualifying speed is 109.066, find a 95% prediction interval estimate of the starting position.
