Question

if there are 13 successful outcomes in a sample with a size of 25, what is the sample proportion? a. 0.52 b. 0.76 c. 0.32 d. 0.96

Explanation:

Step1: Recall sample proportion formula

The formula for sample proportion ($\hat{p}$) is $\hat{p}=\frac{x}{n}$, where $x$ is the number of successful outcomes and $n$ is the sample size.

Step2: Substitute values

Here, $x = 13$ and $n = 25$. So, $\hat{p}=\frac{13}{25}$.

Step3: Calculate the division

$\frac{13}{25}=0.52$.

Answer:

A. 0.52
