The following probability table gives the results of a survey in which infants in the survey are classified as having been immunized against some childhood disease, not immunized, whether the child\'s family has been classified as being below the poverty level, or not below the poverty level.

Below Poverty

Not Below Poverty

Immunized

.05

.55

Not immunized

.15

.25

Are immunization and poverty independent?

Yes, because P(I | P) = P(I)

No, because P(I | P) = P(I)

No, because P(I) + P(P) is not equal to P(IP)

No, because P(I | P) is not equal to P(I)

Solution

Immunization and poverty is not independent as

D) No, because P(I | P) is not equal to P(I)
