<PRE><B>Question 1070258</B>
30C13(0.47)^13*0.53^17=0.1344
--------------------
30C12*0.48^12*0.52^18=0.1000
for 13 is 0.1278
for 14 is 0.1432
for 15 is 0.1410
for 16 is 0.1221
They add to 0.6431
---------------------
Neither votes do 0 and 1 and subtract from 1
0 is .95^30=0.2146
1 is 30*0.05*0.95^29=0.3389
They add to 0.5535
1-0.5535=0.4465 ANSWER
----------------------
Not votes are 0.53
mean is np=30*.53=15.9
variance is np(1-p)=15.9*.47
7.473
sqrt(7.473)=2.73=sd
