Diastolic blood pressure measurements on american men aged 18-44 years follow approximately a normal distribution with µ = 81mmhg and σ = 11mmhg, and for women is also approximately normal with the same sd but a lower mean: µ = 75mmhg. suppose we are going to measure the diastolic blood pressure of n randomly selected men and n randomly selected women in this age 2 group. let e be the event that the difference between men and women will be found statistically significant by a t-test. how large must n be in order to have pr(e) = 0.9
