Chapter 9, Problem 70SE

Members of the millennial generation are continuing to be dependent on their parents (either living with or otherwise receiving support from parents) into early adulthood (The Enquirer, March 16, 2014). A family research organization has claimed that, in past generations, no more than 30% of individuals aged 18 to 32 continued to be dependent on their parents. Suppose that a sample of 400 individuals aged 18 to 32 showed that 136 of them continue to be dependent on their parents.

1. a. Develop hypotheses for a test to determine whether the proportion of millennials continuing to be dependent on their parents is higher than for past generations.
2. b. What is your point estimate of the proportion of millennials that are continuing to be dependent on their parents?
3. c. What is the p-value provided by the sample data?
4. d. What is your hypothesis testing conclusion? Use α = .05 as the level of significance.
