The mean tread life of a manufacturer's best selling tire is known to be 22,560 miles. Because the distribution of individual tire life is positively skewed, it cannot be assumed to be normal. R&D has come up with a new rubber additive that they suspect will increase mean tire life without affecting variability of tire life. A sample of 36 tires with the new additive has a sample mean tread life of 24,470 miles; the sample based estimate of the...

A manufacturer claims that the average tread life of a premium tire exceeds the average tread life of economy tire of the same size by at least 5000 miles. To test this claim, 50 pieces of each type of tires were tested under similar conditions. The premium tire had an average tread life of 43000 miles with a sample standard deviation of 2300, while economy tire had an average tread life of 37500 miles with a sample standard deviation of...

The nicotine content in a single cigarette of a particular brand is a random variable having a probability distribution with a mean of 4.9 milligrams (mgs) and a standard deviation of 0.2 mg. n = 100 of these cigarettes are chosen at random and the nicotine content of each cigarette is measured. What is the probability that the mean nicotine content of this sample is between 4.87 mgs to 4.96 mgs?
