¿A cuantas familias tendríamos que estudiar para conocer la preferencia del mercado en cuanto a las marcas de shampoo para bebe, si se conoce que el número de familias con bebés en el sector de interés es de 15.000 ? El nivel de confianza es de 95%, el margen de error es de 3% , la probabilidad de que ocurra es el 5% calcular la muestra?

{0,1,2,3,4,5,6,20,21,22,23,24,25} the distribution is considered to be: skewed the right, skewed the left, not skewed?

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
