The best point estimate of the population proportion *p* is simply the sample proportion. It's calculated as:
Sample proportion (p̂) = (Number of successes) / (Sample size)
In this case:
p̂ = x / n = 580 / 990 ≈ 0.586
So, the best point estimate of the population proportion *p* is approximately **0.586** or **58.6%**.
