Find a such that P(X >a) = 0.8461.
Select one:
a. 13.96
b. 20.08
c. 18.04
d. 11.92
Explanation / Answer
1)P(X<17) =P(Z<(17-16)/2) =P(Z<0.5)=0.6915
2)at 0.7995 percentile ; z=0.84
for missing value =mean +z*Std deviation =16+2*0.84 =17.68
3)P(X>16.5)=P(Z>0.25)=0.4013
4)P(X>15) =P(Z>-0.5)=0.6915
5) P(X>16.5) =P(Z>0.25)=0.4013
6)P(X<14.5) =P(Z<-0.75)=0.2266
7)P(15.5<X<17)=P(-0.25<Z<0.5)=0.2902
8)P(17 < X < 18) =0.1498
9)P(14.5 < X < 18.4)=0.6583
10) P(X <a) = 0.8461 ; a =18.04
11)P(X>a) =0.8461 ; a =13.96
