Assume the wattage output for 120V household electric motors follows an approximate normal distribution with a mean of 1900W and a standard deviation of 16.7W. a.) What percentage of motors will be able to produce at least 1886W? b.) What output would be higher than 83% of all other motors? c.) Would a motor able to output 1920W be considered unusual? Explain fully using probability.
