A study examined transformer voltage sags and swells. For a sample of transformers built for heavy? industry, the mean number of sags per week was and the mean number of swells per week was . Assume the standard deviation of the sag distribution is sags per week and the standard deviation of the swell distribution is swells per week. Suppose one of the transformers is randomly selected and found to have sags and swells in a week.
a. Find the? z-score for the number of sags for this transformer. Interpret this value.
b. Find the? z-score for the number of swells for this transformer. Interpret this value.
