Question

The table below is the frequency of wins for different postpositions in a horse race. A post position of 1 is closest to the inside, so that horse has the shortest distance to run (Because the number of horses varies from year to year, only the first 10 postpositions are included) Use a 0.05 significance level to test the claim that the Relhood of winning is the same for the different post positions. Based on the result, should better consider the post position of a horse race? Post Position Wins 19 15 12 16 11 10 11 Determine the nut and eative hypotheses H HI Calculate the test att (Round to three decimal places as needed.) Calculate the P-value Palue (Round to four decimal place ascended) What is the conclusion for this hypothesis test? O A Reject Hy. There is insufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different postpositions OB. Falto reject Ho. There is suicient evidence to watat rejection of the claim that the likelihood of winning is the same for the different postpositions. OC. Roject H. There is suicient evidence to warrant rejection of the claim that the hood of winning is the same for the different post position OD. Fail to reject Ho. There is insufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different postpositions

Answer 1

Answer:-

Totest Ho!- wine occur with equal frequency in the different post positionen pact position has a distesent fequery find expected value (19+15+ 19+15+12+16+18+9+8+11+6+ (1) Hi Al feast one of wins than the others.
