Based on the data in the two-way table, the probability of being older than 25 years and having a hemoglobin level above 11 is a: 0.29 b: 0.34 c: 0.54 the probability of having a hemoglobin level above 11 is . a: 0.25 b: 0.3 c: 0.36 being older than 25 years and having a hemoglobin level above 11 a. are b. are not dependent on each other. 20 points : 3

A) 0.29; C) 0.36; A) are

Step-by-step explanation:

There are a total of 128+162 = 290 people that are over 25 years old.  Out of these, there are 84 people with a hemoglobin level above 11; this is a probability of 84/290 = 0.29.

There are 154 people with a hemoglobin level over 11 out of 429 people total; 154/429 = 0.36.

In order for two events to be independent,

P(A∩B) = P(A)·P(B)

The probability that someone is over 25 and has a hemoglobin level above 11 was 0.29.

The probability that someone is over 25 is 290/429; the probability that someone has a hemoglobin level above 11 is 154/429.  This makes

P(A)·P(B) = (290/429)·(154/429) = 0.24

The probabilities are not equal, so the events are not independent; this means they are dependent.
