Use the six steps of hypothesis testing to answer the following question. Remember to determine if the problem is a Z test or T test as that will influence your critical value. You believe you have discovered a topical solution that heals wounds faster. The average number of days it takes to remove stiches after surgery in all hospital patients is 12. In a sample of 29 patients the average number of days to remove stiches is 10.5 with a std dev. Of 1.2 Did your solution lessen the number of days patients had stiches
Molly works for a meat producer, and she needs to determine whether containers of ground beef have the correct fat content. She obtains a random sample of 120 containers of ground beef and finds that 84 percent have the correct fat content. Molly then conducts a hypothesis test of H0:p=0.80H0:p=0.80 versus Ha:p≠0.80Ha:p≠0.80 and calculates a test statistic of 1.10 with a pp-value of 0.273. Which of the following best represents the meaning of the pp-value? If the population proportion is 0.84, the probability of observing a sample proportion of 0.80 is 0.273. A If the population proportion is 0.84, the probability of observing a sample proportion of at least 0.04 less than 0.84 is 0.273. B If the population proportion is 0.80, the probability of observing a sample proportion within 0.04 of 0.80 is 0.273. C If the population proportion is 0.80, the probability of observing a sample proportion at least 0.04 greater than 0.80 is 0.273. D If the…
