Question

Hypergeometric Distribution. Suppose that Z has a hypergeometric distribution with parameters N = 20, M = 7, n = 4.

(a) In Minitab Type 0, 1, 2, 3, 4 in column c10, use the command

MTB > cdf c10;

SUBC > hypergeometric 20 7 4.

to find P(Z < 2) = and P(Z > 2)

(b) Use the “inverse cdf” command which for a given number a between 0 and 1 yields the value of (?) that satisfies P(Z <?) = a, by typing:

MTB > invcdf a ;

SUBC > hypergeometric 20 7 4.

to find the value c in P(Z < c) = 0.992776. The value of c is?
