The data in the following table from the book A Handbook of Small Data Sets ( Hand et al., 1993, p. 36) document the starting positions of the winning horses in 144 races. The starting position listed as 1 is the position of the horse in the starting gate closest to the inside rail of the track, and position 8 is farthest from the rail. Racing officials contend that starting position has no effect on the chance of winning the race.
a. What is the population of interest?
b. Do the data support the racing officials’ contention?
