\\ \tt\longmapsto S=2\pi zx+7\pi z^2

\\ \tt\longmapsto S=\pi z(2x+7z)

\\ \tt\longmapsto 2x+7z=\dfrac{S}{\pi z}

\\ \tt\longmapsto 2x=\dfrac{S}{\pi z}-7z

\\ \tt\longmapsto 2x=\dfrac{S-7\pi z^2}{\pi z}

\\ \tt\longmapsto x=\dfrac{S-7\pi z^2}{2\pi z}

\\ \tt\longmapsto x=\pi z\left(\dfrac{S-7z}{2}\right)

Answer:

<u>Given:</u>

  • S = 2πzx + 7πz²

<u>Isolate x:</u>

  • 2πzx = S - 7πz²

<u>Divide both sides by 2πz:</u>

  • x = (S - 7πz²)/(2πz)
  • x = S/(2πz) - 3.5z

A survey asked whether respondents favored or opposed the death penalty for people convicted of murder. Software shows the resul
scoray [572]

Answer:

The 95% confidence interval for those opposed is: (0.298, 0.334).

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

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

1786 of the 2611 were in favor, so 2611 - 1786 = 825 were opposed. Then

n = 2611, \pi = \frac{825}{2611} = 0.316

95% confidence level

So \alpha = 0.05, z is the value of Z that has a pvalue of 1 - \frac{0.05}{2} = 0.975, so Z = 1.96.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.316 - 1.96\sqrt{\frac{0.316*0.684}{2611}} = 0.298

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.316 + 1.96\sqrt{\frac{0.316*0.684}{2611}} = 0.334

The 95% confidence interval for those opposed is: (0.298, 0.334).

densk [106]

<u>Question</u>

Suppose that a committee is studying whether or not there is excessive time waste in our judicial system. It is interested in the mean amount of time individuals spend at the courthouse waiting to be called for jury duty. The committee randomly surveyed 81 people who recently served as jurors. The sample mean wait time was 4 hours with a sample standard deviation of 1.2 hours. Define the random variables X and \bar{X} in words.

Answer:

(B)

  • X is the amount of time an individual waits at the courthouse to be called for service.
  • \bar{X}  is the mean wait time for a sample of individuals.

Step-by-step explanation:

The random variable X is the amount of time for which each of the prospective juror waits at the courthouse before being called for service.

\bar{X}  is the mean wait time for a the given sample of individuals. In the case given,
