1) Hyperlipidemia in children has been hypothesized to be related to high cholesterol in their parents.The data in Table 5-11 were collected on parents and children. a) What is the probability that one or both parents are hyperlipidemic? b) What is the probability that a child and both parents are hyperlipidemic? c) What is the probability that a child is hyperlipidemic if neither parent is hyperlipidemic? d) What is the probability that a child is hyperlipidemic if both parents are hyperlipidemic?

Solution probability that one or both parents are hyperlipidemic = (13+34+45+42) / (13+34+45+42+83+6) =0.60.

1. 1) Hyperlipidemia in children has been hypothesized to be related to high cholesterol in their
parents.The data in Table 5-11 were collected on parents and children.
a) What is the probability that one or both parents are hyperlipidemic?
b) What is the probability that a child and both parents are hyperlipidemic?
c) What is the probability that a child is hyperlipidemic if neither parent is hyperlipidemic?
d) What is the probability that a child is hyperlipidemic if both parents are hyperlipidemic?
Table 5-11 Hyperlipidemia in Parents and Children
Child Both parents One Parent Neither Parent
Hyperlipidemic Hyperlipidemic Hyperlipidemic
Not Hyperlipidemic 13 34 83
Hyperlipidemic 45 42 6
2) A national survey of graduate students is conducted to assess their consumption of
coffee.Table 5-12 summarizes the data.
Solution
probability that one or both parents are hyperlipidemic
= (13+34+45+42) / (13+34+45+42+83+6)
=0.60
