Caption: Probability that a 60 year old male has a BMI between 30 and 35.
Text: We already computed the probability that BMI is less than 30 [P(x<30)=0.5675], and we also computed the probability that BMI is less than 35 [P(x<35)=0.8413]. These two results can be used to compute the probability that a BMI lies between these two values.This can be computed as follows P(0.17 < Z < 1) = 0.8413 - 0.5675 = 0.2738.
This probability can be thought of as follows P(0.17 < Z < 1) = P(Z < 1) - P(Z < 0.17).
