A study was done to understand the average gestation of mammals. A sample of 40 different species was taken, and the length of gestation was recorded. The average gestation was found to be 194.325 days with a standard deviation of 140.5. Question 16 (3 points) The question of interest is as follows: Do the data provide evidence that the average gestation of mammals is different from 200 days? What is the appropriate set of hypotheses for testing this research question? Using the confidence interval found in the previous question, is = 200 a plausible value for the average gestation of mammals? Question 18 options: No, since the interval contains 200. Yes, since the interval contains 200. Yes, since the interval does not contains 200. No, since the interval does not contains 200
