Problem 3. {Adapted from Rosner page 135] Suppose that the diastolic blood pressures of 3511 year old men are normally distributed with mean El] [mm H g] and variance 1+1. For the same population. the systolic blood pressures are also normally distributed and have a mean of 12D and variance 121. El. What is the probability that a randomly selected person from this population has a DEF less than 9-D? . What DBP represents the so\
