Question 1104729
29. 50C250.68^25*0.32^25=0.0035
30. Mean is np=34; variance is np(1-p)=34*0.32=10.68; sd=sqrt (var)=3.27. This answers 32.
using continuity correction factor z>(39.5-34)/3.27=1.68.  Probability is 0.0465
31. Fewer than 30 is (29.5-34)/3.27 or z<-1.38, probability is 0.0838.
33. For 45, the probability is 50C450.68^45*0.32*5=0.0002. Unusual. The mean is 34 and the sd is 3.27. Most of the probability will involve searches between 31 and 37.
