Question 912914: A typical customer orders at Amazon.com, X( a random variable) is assumed to follow a continous normal distribution with population mean = $16 and population variance = $132. What is the probability that the next customer will order more than $32 of a product(s Answer by ewatrrr(24785) (Show Source):
You can put this solution on YOUR website! *Note:
P(X >32) = 1 - P(x ≤ 32) = 1 - P( z < (32-16)/11.49) = 1 - P(z < 1.3926) = .0819 0r 8.19%
