Problem 1RE

Ergonomics When designing an eye-recognition security device, engineers must consider the eye heights of standing women. (It's easy for men to bend lower, but it's more difficult for women to rise higher.) Listed below are the eye heights (in millimeters) obtained from a simple random sample of standing adult women (based on anthropometric survey data from Gordon, Churchill, et al.). Use the given eye heights to find the (a) mean; (b) median; (c) mode; (d) midrange; (e) range; (f) standard deviation; (g) variance; (h) Q 1 ; (i) Q 3 .
