a) Find the best point estimate of the population proportion p.
(Round to three decimal places as needed.)

Step 1 ：Given that the total number of people polled (n) is 937 and the number of people who said 'yes' (x) is 513.

Step 2 ：The best point estimate of the population proportion p is given by the formula \(p = \frac{x}{n}\), where x is the number of successes (in this case, the number of people who said 'yes') and n is the total number of trials (in this case, the total number of people polled).

Step 3 ：Substitute the given values into the formula: \(p = \frac{513}{937} = 0.5474919957310566\).

Step 4 ：Round the result to three decimal places: \(p = 0.547\).

Step 5 ：Final Answer: The best point estimate of the population proportion p is \(\boxed{0.547}\).
