Repeat Exercise 11 assuming that the population standard deviation s is known to be 11.1 years. Conduct the hypothesis test using a known value of the population standard deviation σ. If we want to use the sample data from Exercise to test the claim that the sample is from a population with a standard deviation less than 1.8 min, we must satisfy the requirements of having a simple random sample and a ...A simple random sample of 25 filtered 100-mm cigarettes is obtained, and the tar content of each cigarette is measured.
