Tarea 6.2 (30 puntos) Instrucciones: Realiza los ejercicios asignados para esta actividad. Debes presentar los procesos necesarios para sustentar la respuesta de los ejercicios. (5 pts. c/u) 1) Usa la tabla A-1 para determinar la distribución binomial para: a) n=2, x=2 p=0.40 = .160 b) n=5, x=4 p=0.99 = .048 c) n=7, x=1 p=0.50 = .055 2) Usa la fórmula de distribución binomial para: a) n = 5, x = 2, p = 0.70 P(x)= n! ( n x ) x ! . p x . q n-x P(2)= 5 ! ( 5 2 ) ! 2 ! x 0.70 2 x 0.3 5-2 P(2)= (10)(0.49)(0.027) = 0.132 b) n = 6, x = 4, q = 0.45 P(x)= n! ( n x ) x ! . p x . q n-x P(4)= 6 ! ( 6 4 ) ! 4 ! x 0.55 4 x 0.45 6-4 P(4)= (15)(0.09150625)(0.2025) = 0.278 3) Calcular la media y la desviación estándar de una distribución de probabilidad discreta usando los datos del ejercicio 2 (parte b). µ = np = (6)(0.55) = 3.3 σ = npq = ( 6 ) ( 0.55 ) ( 0.45 ) = 1.22

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
