Question

question 19 of 28
if there are 26 successes in a sample with a size of 40, what is the sample
proportion?
a. 0.52
b. 0.75
c. 0.26
d. 0.65

Explanation:

Step1: Recall the formula for sample proportion

The formula for sample proportion $\hat{p}$ 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

Here, $x = 26$ and $n=40$. So, $\hat{p}=\frac{26}{40}$.

Step3: Simplify the fraction

$\frac{26}{40}=\frac{13}{20}=0.65$.

Answer:

D. 0.65
