A sample of 500500 full-time employees found that 9696 did not use all of their vacation days last year. However, 116116 of those studied expressed a desire for more vacation time. Based on this sample, if a full-time employee is chosen at random, what is the probability that he or she is content with the vacation allowance? Express your answer as a fraction in lowest terms or a decimal rounded to the nearest millionth.

A random sample of 100 postal employees found that the average time these employees had worked for the postal service was x(bar) = 7 years, with standard deviation s = 2 years. Assume the distribution of the time the population of employees has worked for the postal service is approximately normal, with mean μ. Are these data evidence that μ has changed from the value of 7.5 years of 20 years ago? Carry a test of significance at 1% and...
