n = z² p q

           b²

n=         (z)² N (p) (q) ____

       (e) ² N + [(z)² (p) (q)]

n =          (z)² N (p) (q) ____

       (e) ² (N-1) + [(z)² (p) (q)]

Media muestral=  x1 + x2+ x3… +x n

                                               n

R = XM – X m +UM

IC =  R_

       N c

I C=                   R______

           1+ 3.322 (Log N)

R = X M – X m + 1

MC= L I A+ L S A

                   2

FI= n1

       n           

N1 = n1

N2 = n1+ n2

N n = n1 + n2 + … + nn-1 + n n = n
