Answer:

Var(x)=npq=4.2

Step-by-step explanation:

Given that X is binomial n=20: p=0.70

a) Compute f(12) (to 4 decimals).

=

b) Compute f(16) (to 4 decimals).

=

c) Compute P(x <16) (to 4 decimals).

=

d) Compute P(x <15) (to 4 decimals).

=

e) Compute E(x). =np = 14

f) Compute Var(x) (to 1 decimal) and (to 2 decimals).

Var(x)=npq=4.2
