ne table below lists the frequency of wins for different post positions in a horse race. A ost position of 1 is closest to the inside rail, so that horse has the shortest distance to in. (Because the number of horses varies from year to year, only the first 10 post ositions are included.)

What is the conclusion for this hypothesis test?
OA. Reject Hg. There is insufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different post positions.
OB. Reject H₂. There is sufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different post positions.
