Q1 Assume that the acidity of a lake is a function of both the 502 in the air and the solid waste from surrounding homes and businesses. 302 in the air has an acidity given by N(15,5) while solid waste has an acidity given by N(17,2). Assume ? = 0.5. What is the probability that the acidity of the lake more than 37. A.
