Question 1140728: Consider a normal population with a mean of 50 and standard deviation of 2.Find the probability that a randomly picked number is between 49.1 and 50.15. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z=(x-mean)/sd
so z is between (49.1-50)/2=-.9/2=-0.45
and (50.15-50)/2=0.15/2=+0.075
that probability is 0.2035
