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 the same for the different post positions. Based on the result, should bettors consider the post position of a horse race? Post Position Wins Determine the null and alternative hypotheses. Ho: H₂: O No O Yes 19 (Round to four decimal places as needed.) 15 Calculate the test statistic, ². x² = (Round to three decimal places as needed.) Calculate the P-value.

4. Michael is running for president. The proportion of voters who favor Michael is 0.8. A simple random sample of 100 voters is taken. Assume that n/N < 0.05.

The M&M/Mars candy company does a lot of market research to determine the most appealing mix of colors in M&M candies.  Recently, one mix was: Purple 20%; Yellow 20%; Red 20%; Orange 10%; Green 10%; Blue 10% and Brown 10%.  Suppose you reach into a bag of M&M candies and draw out ONE candy at random. What is the likelihood of drawing a Purple candy?
