Question 912046: The attendance at an athentic stadium is normally distributed with a mean of 20,000 people and variance of 2,000 find.
A. The percentage of attendance figures which falls between 19,500 and 22,000 people.
B. The percentage of attendance above 23,000 people. Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! m = 20,000, sd = sqrt(2000) = 44.7214
P(19500 < x <22000) = normalcdf(19500,22000,20000,44.7214)
