Suppose that X1 is a uniformly distributed random variable, X2 is a normally distributed random variable, and X3 is an exponentially distributed random variable. For each of the following statements, indicate whether it applies to X1 , X2 , and/or X3 . Check all that apply. X1 X2 X3 (uniform) (normal) (exponential) Probabilities are given by areas under the graph of the probability density function f(x). The graph of the probability density function is perfectly symmetrical about the mean. Smaller values of X are more likely than larger values of X
