algunas formulas de probabilidad y estadistica

n = z² p q
          



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
