VIII. USE THE INFORMATION BELOW TO ANSWER PROBLEMS 25 THROUGH 27. Electric power plants that use water for cooling their condensers sometimes discharge heated water into rivers, lakes, or oceans. It is known that water heated above certain temperatures has a detrimental effect on the plant and animal life in the water. Suppose it is known that the increased temperature of the heated water discharged by a certain power plant in any given day has a normal distribution with a mean of 2.8 degrees Celsius and a standard deviation of 0.6 degrees Celsius. Suppose a sample of 35 days was collected. You are interested in the probability that the mean increase in temperature of the discharged water for the sample exceeds 2.6 degrees Celsius. 25.
