Question 1164282: A producer of soft drinks believes that her brand has a 10% market share. Determine the
probability of observing 211 or fewer consumers out of a random sample of 2 500 consumers
who prefer her brand of soft drink. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! 211/2500 is 0.0844
find probability 0.0844 or less with n of 2500
z=(0.0844-0.10)/sqrt(0.1*0.9/2500)
=-0.0156/.006
=-2.6
probability z<-2.6 is 0.00466
