A university in Victoria is investigating expanding its evening programs. It wants to target people aged between 25 and 35 years, who have completed high school but did not complete a university degree. To help determine the extent and type of offerings, the university needs to know the size of its target market. A survey of 320 adults aged between 25 and 35 years 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 Completed some vocational study

4 A university graduate

The responses are recorded and stored in file EDUCATION.xlsx. In 2019, there were about 1,147,315 people between the ages of 25 and 35 in Victoria. Estimate with 95% confidence the number of adults in Victoria between 25 and 35 years of age who were in the market segment the university wishes to target.
