Question 1158008: If the height of college students are normally distributed with mean 69 and variance 9, find the probability that 65≤x≤70 Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! variance is 9
sd is sqrt(V)=3
so z=(x-mean)/sd and (70-69)/3 is 1/3 and (65-69)/3= -4/3
the probability of z between -4/3 and +1/3 is 0.5393
