A police officer would like to estimate the proportion of petty theft cases that have gone unsolved in a large city. He takes a
nata0808 [166]

Answer:

0.625 \pm 1.645*0.0571

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

\pi is the estimate

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}, also called the critical value.

The standard error is:

s = \sqrt{\frac{\pi(1-\pi)}{n}}

90% confidence level critical value

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.955, so z = 1.645.

Estimate:

72 petty theft cases and finds 45 of these have gone unsolved.

So \pi = \frac{45}{72} = 0.625

Standard error:

s = \sqrt{\frac{\pi(1-\pi)}{n}} = \sqrt{\frac{0.625*0.375}{72}} = 0.0571

Answer:

0.625 \pm 1.645*0.0571
