A California university is investigating expanding its evening programs. It wants to target people between 25 and 55 years old who have completed high school but did not complete college or university. To help determine the extent and type of offerings, the university needs to know the size of its target market. A survey of 320 California adults was drawn and each person was asked to identify his or her highest educational attainment. The responses are:
1. Did not complete high school
2. Completed high school only
3. Some college or university
4. College or university graduate
The Statistical Abstract of the United States (2012, Table 16) indicates that there are 15,753,000
Californians between the ages of 25 and 55. Estimate with 95% confidence the number of Californians between 25 and 55 years of age who are in the market segment the university wishes to target.
