Scenario: The data table called NC Births contains a random sample of 1,000 individuals drawn from a larger data set from the state of North Carolina.3 In 2004, the state gathered and released an anonymized data from a large number of recent births. The data table includes several attributes of the mother, father, and baby.

For each of the following questions, use JMP to create a suitable contingency table and report on the probability of sampling one person who satisfies the specified events.

What is the probability that we sample an individual who is a:

a. smoker with a premature baby

b. smoker with a low birth weight baby

c. mature mom and smoker Finally, use your responses to consider the question of independence:

d. Are the events “smoker” and “low birth weight” independent? Explain.
