A tire company claims that the lifetimes of its tires average 49750 miles. The standard deviation of tire lifetimes is known to be 4750 miles. You sample 75 tires and will test the hypothesis that the mean tire lifetime is at least 49750 miles against the alternative that it is less. Assume, in fact, that the true mean lifetime is 49250 miles. It is decided to reject H0 if the sample mean is less than 49150. Find the level and...

The union for a particular industry has determined that the standard deviation of the daily wages of its workers is $19. A random sample of 70 workers in this industry has a mean daily wage of $117. Find a 90% confidence interval for the true mean daily wage of all union workers in the industry. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place.
