Question 333666
 Assume the population of heights of female college students is approximately normally distributed with mean of 46 inches and standard deviation of 4.00 inches. A random sample of 18 heights is obtained. Find the proportion of female college students whose height is greater than 45 inches.
---
z(45) = (45-46)/4 = -1/4
---
P(x > 45) = P(z > -1/4) = 0.5987
