a) find the best point estimate of the population proportion ( p ).
(round to three decimal places as needed.)
Step1: Recall the formula for point - estimate of population proportion
The formula for the point - estimate of the population proportion \(p\) is \(\hat{p}=\frac{x}{n}\), where \(x\) is the number of successes and \(n\) is the sample size.
Step2: Substitute the given values into the formula
Given \(n = 904\) and \(x = 576\), we have \(\hat{p}=\frac{576}{904}\).
Step3: Calculate the value
\(\frac{576}{904}\approx0.637\)
