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

Olympic volleyball player Bev Oden averaged 3.42 "kills" (spikes that end a rally) per game. Predict her number of kills in a 5

damaskus [11]

Answer: 17.1

Step-by-step explanation:

If she averages 3.42 kills per game, she should average that for each of the 5 games. You need to multiply 3.42 times 5 for the total of 5 games.

3.42 x 5 = 17,1

Ann went to the store after school 5 days this week. Each day, she bought a sandwich and a comic book. She spent a total $50 of

Lubov Fominskaja [6]

<em>In total 5 days, she has paid:</em> <em>5 x $2 = $10 </em><em>for the sandwiches</em>

<em>In total 5 days, she has paid: </em><em>$50 - $10 = $40 </em><em>for the comics</em>

<em>So, she paid: </em>$40 / 5 = $8<em> for each comic</em>
