A politician claims that the mean salary for managers in his state is more than the national mean, $83,000. Assume the the population is normally distributed and the population standard deviation is $9400. The salaries (in dollars) for a random sample of 30 managers in the state are listed. At α = 0.04 is there enough evidence to support the claim? Use technology 83,077 72,906 94,387 89,800 73,672 78,747 90,948 91,023 95...

As the population ages, there is increasing concern about accident-related injuries to the elderly. An article reported on an experiment in which the maximum lean angle-the farthest a subject is able to lean and still recover in one step-was determined for both a sample of younger females (21-29 years) and a sample of older females (67-81 years). The following observations are consistent with summary data given in the article: YF: 28, 36, 31, 27, 28, 32, 31, 36, 32, 26...
