Module 5 Exam Exam Page 1 Suppose that you take a sample of size 18 from a population that is not normally distributed. Can the sampling distribution of xx be approximated by a normal probability distribution? No, the sampling distribution of xbar cannot be approximated by a normal probability distribution because the population is "not normally" distributed and the sample size is less than 30. Answer Key Suppose that you take a sample of size 18 from a population that is not normally dis...

Exam Page 1 A new drug is introduced that is supposed to reduce fevers. Tests are done with the drug. The drug is given to 60 people who have fevers. It is found that the mean time that it takes for the fever to get back to normal for this test group is 350 minutes with a standard deviation of 90 minutes. Find the 80% confidence interval for the mean time that the drug will take to reduce all fevers for all people. Case 1: Large population and large sample size n=60 =350 s=90 z=1.282 xx ...
