The average number of turkeys per flock in Kennebec County is 38 with a standard deviation of 4.
A. What size flock would have a z score of --1.5?
Use x = z*s + u
x = -1.5*4 + 38
x = 32
----------------------
B. What percent of flocks would have expected to be smaller than A)?
Solution: P(z < -1.5) = normalcdf(-100,-1.5) = 0.0668 = 6.68%
