Accepted Solution

A:

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

(154-69)/(429-139)

=85/290

=0.2931~0.29

Answer: A. 0.29

The probability of having a hemoglobin level above 11 is

P(H>11)

=154/429

=0.35897~0.36

Answer: C:0.36

Being older than 25 years and having a hemoglobin level above 11

Are not dependent on each other because w have not been told about any factors that were included in selection of sample.

Answer: B.are not
