Consider the following hypothetical survey results of 18- to34-year-olds in a certain country, in response to the question "Areyou currently living with your family?"
(a)
Develop the joint probability table for these data and use it toanswer the following questions.
(b)
What are the marginal probabilities?
P(18- to 34-year-old woman)
=
P(18- to 34-year-old man)
=
P(responded yes)
=
P(responded no)
=
(c)
What is the probability of living with family given you are an18- to 34-year-old woman in this country? (Round your answer tofour decimal places.)
(d)
What is the probability of living with family given you are an18- to 34-year-old man in this country? (Round your answer to fourdecimal places.)
(e)
What is the probability of an 18- to 34-year-old in this countryliving with family?
(f)
If, in this country, 49.6% of 18- to 34-year-olds are male,do you consider this a good representative sample? Why?
Since
P(18- to 34-year-old man) =
in this sample,this ---Select--- seems does notseem like a good representative sample based on gender.
