Question 1195484
129*0.26=33.54 use 33.5 
129*0.437=56.373 so use 56.5 continuity correction factor.
the mean is np or 129*0.31=39.99. 
variance is np(1-p)=24.3939
sd is sqrt(24.3939)=4.94
want z=(56.5-39.99)/4.94
=16.51/4.94
=+3.34
z=(33.5-39.99)/4.94=-1.01
probability of z in that range is 0.8433
