13.13 Let X have distribution N(0, 1). From Table 7 in the appendix, obtain a sample of size 20 from this distribution. Let Y = |X].

(a) Use this sample to compare P[1 < Y <2] with the relative frequency of that event.

(b) Compare E(Y) with the sample mean Y.

(c) Compare the cdf of Y, say F(t) = P(Y) with F, the empirical cdf of Y.
