Consider a purely probabilistic game that you have the opportunity to play. each time you play there are n potential outcomes x1, x2, xn (each of which is a specified gain or loss of euros). these outcomes x1, x2, xn occur with the probabilities p1, p2, pn respectively (where p1 + p2 + + pn = 1.0 and 0 < = pi < = 1 for each i). positive xi values mean a gain of |xi| euros and negative values mean a loss of |xi| euros. assume that x1, x2, xn and p1, p2, pn are all known quantities. furthermore, assume that each play of the game takes up one hour of your time, and that only you can play the game (you can't hire someone to play for you). let m be the game's expected value. that is, m = p1*x1 + p2*x2 + + pn*xn. let s be the game's standard deviation. that is, s = squareroot( p1 * (x1 - m)^2 + p2 * (x2 - m)^2 + + pn * (xn - m)^2 ).

Need now max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
