A prison official wants to estimate the proportion of cases of recidivism. Examining the records of 250 convicts, the official d
son4ous [18]

Answer:

For this sample, the estimated standard error is of 0.0277

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Examining the records of 250 convicts, the official determines that there are 65 cases of recidivism.

This means that n = 250, p = \frac{65}{250} = 0.26

For this sample, the estimated standard error is

s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.26*0.74}{250}} = 0.0277

For this sample, the estimated standard error is of 0.0277
