Question

The number of successes and the sample size are given for a simple random sample from a population. Determine the sample proportion, $\hat { p }$.
-x = 69, n = 125 
A) $\hat { p } = 0.552$
B) $\hat { p } = 0.572$
C) $\hat { p } = 0.502$
D) $\hat { p } = 0.652$

Quizplus · Accepted Answer

The sample proportion, $\hat { p }$, is calculated as the number of successes (x) divided by the sample size (n). Thus, $\hat { p } = \frac{69}{125} = 0.552$.
