For a sample of 106 transformers built for heavy industry, the mean and standard deviation of the number of sags per weeks were 363 and 33, respectively; also, the mean and standard deviation of the nur swells per week were 179 and 28, respectively. Consider a transformer that has 421 sags and 77 swells in a week. Complete parts a and b below. a. Would you consider 421 sags per week unusual, statistically? Explain. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Yes. The z-score is meaning that this is an outlier and almost every other transformer has fewer sags. (Round to two decimal places as needed.) O B. Yes. The z-score is meaning that this is an outlier and almost every other transformer has more sags. (Round to two decimal places as needed.) OC. No. The z-score is meaning that less than approximately 68% of transformers have a number of sags closer to the mean. (Round to two decimal places as needed.) O D. No. The z-score is, meaning that the number of sags is not unusual and is not an outlier. (Round to two decimal places as needed.) This cannot be determined, since the JOR is not provided and cannot he found from the provided information.
