How many standard deviations is that he difference found in part (a)] c. Convert Jordan's height to a z score d. If we consider "usual" heights to be those that convert to Z scores between - 2 and 2, is Jordan's height usual or unusual? a. The positive difference between Jordan's height and the mean is cm. b. The difference is standard deviations. (Type an integer or decimal rounded to two decimal places as needed) c. The z score is (Type an integer or decimal rounded two decimal places as needed.) d. Is Jordan's height usual or unusual? Usual Unusual
