The chemical benzene is highly toxic to humans. However, it is used in the manufacture of many medicine dyes, leather, and coverings. Government regulations dictate that for any production process involving benzene, the water in the output of the process must not exceed 7950 parts per million (ppm). It is known from historical data that the standard deviation Ïƒ is 100 ppm. Required:
a. What is the probability that the sample average in this experiment would exceed the government limit if the population mean is equal to the limit?
b. Is an observed = 7960 in this experiment firm evidence that the population mean for the process exceeds the government limit?

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
