That is, determine the lower and upper limits for the middle 90% of BMI scores (i.e. 5% will be less than the lower limit and 5% will be greater than the upper limit). Round answer to the nearest hundredth of a kg/m2 (i.e. 23.45 kg/m2). The middle 90% of BMI scores lie between ______ kg/m2 and _____ kg/m2. (enter lower limit first).
