To find the point estimate for the proportion of people who performed volunteer work, we use the formula:

$\text{Point Estimate} = \frac{\text{Number of people who volunteered}}{\text{Total number of people surveyed}}$

Given:

• Number of people who volunteered = 527
• Total number of people surveyed = 1300

Now, calculating the point estimate:

$\text{Point Estimate} = \frac{527}{1300} \approx 0.405$

Rounded to three decimal places, the point estimate for the proportion of people who performed volunteer work during the past year is 0.405.

Tip: Always ensure your sample size is large enough for accurate estimates, especially when making predictions based on proportions.
