within 1 standard deviation of the meanwhat percent of men are between 68" and 72" ?.....between 0 and 2 (z-values)thats 47%, or .47OR: the probability that a man is between 68" and 72" is .47notation:P(68 < x < 72)or P(0 < z < 2)
ex) find P(z 1.37) ?the TOTAL has to be 1so the area is 1 - .9147= .0853you do: [draw the picture and find the answer, to four decimal places]ex) P(z < -1.77) ex) P(z > .58) ex) P(z < 2.33) ex) P(z > 2.33) ex) P(z < -2.33)note: what determines which side youshade?note that its thesame as theprevious answer,because ofsymmetry
