Answer:

Step-by-step explanation:

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

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

=[tex]0.1144[/tex]

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

=[tex]0.1304[/tex]

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

=[tex]0.7624[/tex]

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

=[tex]0.5836[/tex]

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

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

Var(x)=npq=4.2
