An energy study found that household use of electricity had a mean of 682 and a standard deviation of 551 kilowatt-hours. Complete parts (a) and (b). a. Suppose the distribution of energy use was normal. Using a table, calculator, or software that can give normal probabilities, find the proportion of households with electricity use greater than 1000 kilowatt-hours. The proportion of households with electricity use greater than 1000 kilowatt-hours is 0.28 . (Round to the nearest hundredth as needed.) b. Based on the mean and standard deviation given, do you think that the distribution of energy use actually is normal? Why or why not? No, the distribution of energy use does not appear to be normal since 0 has a z-score of only (0-682) / 551=-1.24, yet energy use cannot be negative Yes, the distribution of energy use appears to be normal since the value 682 - 551=131 is positive.
