Question 25 1 pts 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. In fact, the Environmental Protection Agency has set guidelines requiring the sample mean temperature of discharged water to be at most 2.6 degrees Celsius. Suppose it is known that the temperature of the heated water discharged by a certain power plant in any given day follows a 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 at a power plant and the temperature of discharged water was recorded each day. You are interested in the probability that the power plant has not met the EPA's guidelines. 25. Pick the equation most appropriate to deal with the problem above. a) 2:35;]! 0' 13) x=g+za _x__E c) 207\"; d) p(x)-(an)p'(1p)\"" Question 26 1pts 26.
