1) S2= p * (1-p) =.9 * (1-.9) = .09
2) V2= (0.015)2 = 0.000225
3) NI = S2/ V2 = 0.09/.000225 = 400
4) N = NI/(1+( NI/n)) = 400/(1+(400/3728))= 361.24 = 361
5) Muestra / Universo = 361/3728 = 0.096 = a
6) Alumno * a =
a. 0.096 * 834 = 80.06 = 80
b. 0.096 * 353 = 33.88 = 34
c. 0.096 * 415 = 39.84 = 40
d. 0.096 * 746 = 71.61 = 72
e. 0.096 * 734 = 70.46 = 70
f. 0.096 * 646 = 62.01 = 62
