Question 1115036
np = mean = 14 * 0.6 = 8.4
:
nq = 14 * (1-0.6) = 5.6
:
Note np = 8.4 > or = 5 and nq = 5.6 > or = 5 
:
variance = 8.4 * (1-0.6) = 3.36
:
standard deviation = square root(3.36) = 1.833
:
z-score = (5 - 8.4) / 1.833 = -1.85
:
lookup z-score in table of z-scores to find associated probaility
:
Probability (X < 5) = 0.0322
