Question

Reporting cheating What proportion of students are willing to report cheating by other students? A student project put this question to an SRS of $172$ undergraduates at a large university: “You witness two students cheating on a quiz. Do you go to the professor?” Only 19 answered “Yes.”$3$

Short answer

The sample proportion is$\hat{p}=11.05\%$.

Step-by-step solution

Given Information

$n=\text{Sample size}=172$

$x=\text{Number of successes}=19$

Explanation

The population proportion $p$is estimated by the sample proportion $\hat{p}$.

The sample proportion is the number of successes divided by the sample size.

$\hat{p}=\frac{x}{n}=\frac{19}{172}\approx 0.1105=11.05\%$.
