10.Operating temperatures of two models of portable electric generators follow a normal distribution. For generator I, the mean temperature is 1 = 148F with standard deviation 1 = 25F. For generator II, the mean temperature is 2 = 143F with standard deviation 2 = 8F. At peak power demand, generator I was operating at 166F, and generator II was operating at 165F.

(a) At peak power output, both generators are operating at about the same temperature. Relative to the operating characteristics, is one a lot hotter than the other? Explain.

(b) Convert the peak power temperature for each generator to standard z units. Then locate both z scores under a standard normal curve. Could one generator be near a meltdown? Which one? Explain your answer.
