1.Yes,When conducting a stratified sample of the adult population of a city, there are various demographic, socio-economic, and geographic factors that could be used as strata.

• Age Groups: Stratifying by age groups such as 18-24, 25-34, 35-44, 45-54, 55-64, 65 and above.

• Income Levels: Stratifying by income brackets, such as low-income, middle-income, and high-income earners.

2.To ensure an accurate representation of part-time and full-time employees in the entire workforce through a stratified sample, we start by assessing the proportions of each group:

• Part-time staff: 150 employees

• Full-time staff: 550 employees

• Total staff: 700 employees

The proportions are calculated as follows:

• Part-time staff proportion: 150 / 700 ≈ 0.2143

• Full-time staff proportion: 550 / 700 ≈ 0.7857

Next, we allocate 20 interviews proportionally:

• Number of interviews for part-time staff: 0.2143 * 20 ≈ 4.286 → rounded to 4

• Number of interviews for full-time staff: 0.7857 * 20 ≈ 15.714 → rounded to 16

In conclusion, conduct 4 interviews with part-time staff and 16 interviews with full-time staff to ensure an accurate reflection of the two groups' proportions in the entire workforce.
