- represents the summary statistics for 44 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds. n = 44; = 40.76 pounds; s = 5.12 pounds a) kdentify the null and alternative hypotheses? Ho: =V 40 H.:p>v40 b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? O left-tailed O right-tailed O two-tailed c) Identify the appropriate significance level. 0.05 d) Calculate your test statistic. (Round your final answer to two decimal places.) e) Calculate your p-value. (Round your final answer to four decimal places.) f) Do you reject the null hypothesis? O We reject the null hypothesis, since the p-value is less than the significance level. O We reject the null hypothesis, since the p-value is not less than the significance level. O We do not reject the null hypothesis, since the p-value is less than the significance level. O We do not reject the…Use Welch's T-test to find the t-test statistic using the given information: X-bar1=1.95, X-bar2=2.34, S1=.97, S2=.89, n1=35, n2=29 for the following hypothesis test: H0: u1-u2=0 vs Ha: u1-u2 does not equal 0.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.

- 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…Scientist Irish used a paired t-test to test the effectiveness of a drug she is developing. She obtained a p-value = 0.005 (she used α = 0.05). Suppose the drug actually works.
