For a normally distributed population, mean of 6.5 and standard
deviation of 4, compute:
a. The probability of picking one item from the population and having it fall between 6.5 and 14.5
----
z(6.5) = (6.5-6.5)/4 = 0
---
z(14.5) = (14.5-6.5)/4 = 2
----
P(6.5 < x < 14.5) = P(0 < z < 2) = normalcdf(0,2) = 0.4772
