b. Confidence interval
c. Margin of error

Answer 1

The point estimate for the proportion of people who did volunteer work during the past year is represented by the symbol p-hat and can be calculated by dividing the number of people who said they did volunteer work by the total number of survey respondents.

Step-by-step explanation:

The point estimate for the proportion of people who did volunteer work during the past year is represented by the symbol p-hat. It is calculated by dividing the number of people who said they did volunteer work by the total number of survey respondents.

In this case, the survey asked 1,294 people and 518 of them said they did volunteer work. Therefore, the point estimate for the proportion of people who did volunteer work during the past year is p-hat = 518/1294 = 0.4.
