A. p= 0.262. The symbol p is used to represent a sample proportion

B. p = 0.213 The symbol is used to represent a sample proportion

D. P^ = 0.213. The symbol is used to represent a sample proportion

Solution

There are 1289 + 457 + 397 = 2143 people in the survey.

We use P^ as symbol for sample proportion.

Thus,

P^ = x/n = 457/2143 = 0.21325245

Thus, it is OPTION D: P^ = 0.213. The symbol is used to represent a sample proportion. [answer, D]
