Step 1 ：A survey was conducted by a reputable polling organization on 2325 adults aged 18 and older in a certain large country. The survey found that 427 of these adults have donated blood in the past two years.

Step 2 ：We are asked to obtain a point estimate for the population proportion of adults in the country aged 18 and older who have donated blood in the past two years.

Step 3 ：The point estimate for the population proportion, denoted as \( \hat{p} \), is calculated by dividing the number of adults who have donated blood by the total number of adults surveyed.

Step 4 ：Substituting the given values into the formula, we get \( \hat{p} = \frac{427}{2325} \).

Step 5 ：Calculating the above expression, we get \( \hat{p} = 0.18365591397849462 \).

Step 6 ：Rounding to three decimal places as needed, we get \( \hat{p} = 0.184 \).

Step 7 ：Final Answer: The point estimate for the population proportion of adults in the country aged 18 and older who have donated blood in the past two years is \( \boxed{0.184} \).
