 Question 611707: on average, junior girls own 10 pairs of shoes with a standard deviation of 1.5 shoes. the distribution of shoes follows an approximately normal curve. what is the probability of selecting a junior who owns 12 or more pairs of shoes?Answer by stanbon(57377)   (Show Source): You can put this solution on YOUR website!on average, junior girls own 10 pairs of shoes with a standard deviation of 1.5 shoes. the distribution of shoes follows an approximately normal curve. what is the probability of selecting a junior who owns 12 or more pairs of shoes? ------ z(12) = (12-10)/1.5 = 2/1.5 = 4/3 ------ P(x >= 12) = P(z >= 4/3) = 0.0912 ========================= Cheers, Stan H. ===============
