The table below lists the frequency of wins for different post positions in a horse race. A post position of 1 is closest to the inside rail, so that horse has the shortest distance to run. (Because the number of horses varies from year to year, only the first 10 post positions are included.) Use a 0.05 significance level to test the claim that the likelihood of winning is the same for the different post positions. Based on the result, should bettors consider the post position of a horse race? Post Position 7 Wins Determine the null and alternative hypotheses. Ho: Wins occur with equal frequency in the different post positions. H₁: At least one post position has a different frequency of wins than the others. 20 No O Yes needed.) 2 14 3 10 Calculate the test statistic, ² x² = 26.696 (Round to three decimal places as needed.) Calculate the P-value P-value = [0.11 (Round to four decimal places What is the conclusion for this hypothesis test? O A. Fail to reject Ho. There is sufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different post positions. ⒸB. 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 post positions. OC. Reject Ho. There is insufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different post positions. O D. Reject Ho. There is sufficient evidence to warrant rejection of the claim that the likelihood of winning is the same for the different post positions. Based on the result, should bettors consider the post position of a horse race? 14 6 11 2 10 10

Are Republicans more likely than Democrats to display the American flag in front of their residence on the Fourth of July? A simple random sample of 618 Republicans were surveyed and 408 said they display the flag on the Fourth of July. Another simple random sample of 615 Democrats were surveyed and 394 said they display the flag on the Fourth of July. Let p1p1 be the proportion of all Republicans who display the American flag on July 4th and p2p2 be the proportion of all Democrats who display the American flag on July 4th. What can be concluded at the αα = 0.10 level of significance?  H0:H0:  Select an answer μ p1-p2 μ1-μ2 μd p  Select an answer ≠ < > =  (please enter a decimal)     H1:H1:  Select an answer μ p1-p2 μd p μ1-μ2  Select an answer ≠ > = <  (Please enter a decimal) The test statistic ? z t  = (please show your answer to 3 decimal places.)

A man was buying shoes wheb a salesperson commebted on hiw small his feet were. After telling her she had a lousy sales technique, he decided to inveatigate if he really does have feet that are smaller than the typical american man.
