The weight X of babies (of a fixed age) is normally distributed with mean μ = 212 ounces and standard deviation σ = 25 ounces. Doctors would also be concerned (not necessarily alarmed) if a baby is among the upper 10 percent in weight. Find the cut-off weight u, above which the doctors will be concerned. The weight X of salmon caught in a river is normally distributed with mean μ = 24 pounds and standard deviation σ = 6...
