This question has 4 parts. A chemical plant can dispose a certain amount of wastewater into a river. The Environmental Protection Agency (EPA) takes samples of the river water at several locations downstream from the plant. If the plant complies with the EPA regulations, the population mean number of toxic particles in the water is u : 50 parts per million (ppm). Each day, the EPA selects 36 water samples and computes the average number of toxic particles, and then uses this information to determine if they should conclude that the population mean number of toxic particles is greater than 50 ppm. If so, the owner of the plant will be ned. Use the hypotheses H0 : p, g 50 ppm and HG : pi > 50 ppm. It is known that the population standard deviation, 0, is 8 ppm of toxic particles. iv) Due to a change in the personnel responsible for monitoring the quality of the plant's wastewater, the population mean number of toxic particles in the water during a given month is p, = 54.1 ppm. The population standard deviation remained the same with or = 8 ppm. What is the probability that on a given day this month, the average amount of toxic particles determined from 36 water samples will not result in the owner of the plant being ned?
