Bao Xishun is the world's tallest man with a hieght of 92.95 in. (or 7ft, 8.96 in.). men have hieghts witha mean of 69.6in and a standard deviation of 2.8 in.
1) convert Boa's height to a z score
2) does Boa's height meet the criterion of being unusual by corresponding to a z score that does not fall between -2 and 2?
