Winning team data were collected for teams in different sports, with the results given in the accompanying table. Use a 0.05 significance level to test the claim that home/visitor wins are independent of the sport. Given that among the four sports included here, baseball is the only sport in which the home team can modify field dimensions to favor its own players, does it appear that baseball teams are effective in using this advantage? Click the icon to view the data table. Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: Basketball games are more likely to win at home than any other sport. H₁: Basketball games are not more likely to win at home than any other sport. OB. Ho: Basketball games are not more likely to win at home than any other sport. H₁: Basketball games are more likely to win at home than any other sport. OC. Ho: The home/visitor win is independent of the sport. H₁: The home/visitor win is not independent of the sport. O D.

This question: 5 point(s) possible In a study of 823 randomly selected medical malpractice lawsuits, it was found that 477 of them were dropped or dismissed. Use a 0.01 significance level to test the claim that most medical malpractice lawsuits are dropped Which of the following is the hypothesis test to be conducted? OA. Ho: p=0.5 H₁: p>0.5 OC. Ho: p=0.5 H₁: p 0.5 H₁: p=0.5 OF. Ho: p0.5 H₁: p=0.5 WA (C) dismissed.
The table below includes results from polygraph (lie detector) experiments conducted by researchers. In each case, it was known if the subjected lied or did not lie, so the table indicates when the polygraph test was correct. Use a 0.05 significance level to test the claim that whether a subject lies is independent of the polygraph test indication. Do the results suggest that polygraphs are effective in distinguishing between truth and lies? Determine the test statistic. (Round ofd to 3 decimal places) Find the P-Value What is the conclusion? (In case you are using excel, I will appreciate if you explain the steps of finding the test statistic and the P-value....But this is not a must)
(b) (c) (d) What is the value of the sample test statistic? Find (or estimate) the P-value. Based on your answers in parts (a) to (c), will you reject or fail to Teject the null hypothesis? Are the data statistically significant at level a? 6. Professor Jennings claims that only 35% of the students at Flora College work while attending school, Dean Benata thinks that the professor has underestimated the number of students with part-time or full-time jobs. A random sample of 76 students shows that 36 have jobs. Do the data indicate that more than 35% of the students bave jobs? Use a 5% level of significance. What are we testing in this problem? i) single proportion ii) single mean a) What is the level of significance? State the null and alternate hypotheses. what sampling distribution will you use? What assumptions are you making? b) What is the value of the sample test statistic? c) Find (or estimate) the P-value. d) Based on your answers in parts (a) to (c), will you reject or fail to…
