Question 1155876: Assume the random variable X is normally distributed with mean 50 and standard deviation 7. Compute the probability P(34< x < 59) Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! z=(x-mean)/sd
=(34-50)/7=-16/7
=(59-50)/7=9/7
z is between those two values
that probability is 0.8896
