Answer:
Explanation:
A world region is a large primary division of the world used in higher education — originally in anthropology, but then also in geography and history, and as the basis for area studies.
Answer:
The answer is B
Explanation:
Because that's what he did
The answer is C. keep enough strength in the senate to protect southern interests
Back then, Slavery is almost a way of life of southerners.Back then, the productions amount in northern part of USA is way more than the south. And the Northerners did that without slavery
In 1808 , the congress abolished slave trading with Africa, making the economic difference between the south and north separated even further
In order to protect their own interest, they want slavery to extend to the north so they have enough strength in the senate to protect its legality
The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less is 0.0020
<h3>What is probability? </h3>
Probability can be defined as the likelihood of an event to occur. In statistics, the mean of the sample distribution typically shows the probability of the population.
From the parameters given:
- The sample size (n) = 55 patients
- Let's assume that the mean (x) = 32 (i.e. 58.2%) of the patients
The sample proportion
can be computed by using the expression:
![\mathbf{\hat p = \dfrac{x}{n}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Chat%20p%20%3D%20%5Cdfrac%7Bx%7D%7Bn%7D%7D)
![\mathbf{\hat p = \dfrac{32}{55}}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Chat%20p%20%3D%20%5Cdfrac%7B32%7D%7B55%7D%7D)
![\mathbf{\hat p =0.582}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Chat%20p%20%3D0.582%7D)
If the percentage of the probability of all patients in the emergency room = 0.75
The probability that the proportion of patients who wait less than 30 minutes is 0.582 or less can be computed as:
![\mathbf{( \hat P \leq 0.582) = P \Big( \dfrac{\hat p - p}{\sqrt{\dfrac{p(1-p)}{n}}} \leq \dfrac{0.582 - 0.75}{\sqrt{\dfrac{0.75(1-0.75)}{55}}} \Big )}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28%20%5Chat%20P%20%5Cleq%200.582%29%20%3D%20P%20%5CBig%28%20%5Cdfrac%7B%5Chat%20p%20-%20p%7D%7B%5Csqrt%7B%5Cdfrac%7Bp%281-p%29%7D%7Bn%7D%7D%7D%20%5Cleq%20%5Cdfrac%7B0.582%20-%200.75%7D%7B%5Csqrt%7B%5Cdfrac%7B0.75%281-0.75%29%7D%7B55%7D%7D%7D%20%5CBig%20%29%7D)
![\mathbf{( \hat P \leq 0.582 )= P \Big( Z \leq \dfrac{-0.168}{\sqrt{0.003409}} \Big )}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28%20%5Chat%20P%20%5Cleq%200.582%20%29%3D%20P%20%5CBig%28%20Z%20%5Cleq%20%5Cdfrac%7B-0.168%7D%7B%5Csqrt%7B0.003409%7D%7D%20%5CBig%20%29%7D)
![\mathbf{( \hat P \leq 0.582) = P \Big( Z \leq -2.88 \Big )}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28%20%5Chat%20P%20%5Cleq%200.582%29%20%3D%20P%20%5CBig%28%20Z%20%5Cleq%20-2.88%20%5CBig%20%29%7D)
From the Z distribution table:
![\mathbf{( \hat P \leq 0.582) = 0.00198}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28%20%5Chat%20P%20%5Cleq%200.582%29%20%3D%200.00198%7D)
![\mathbf{( \hat P \leq 0.582) \simeq 0.0020}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28%20%5Chat%20P%20%5Cleq%200.582%29%20%5Csimeq%200.0020%7D)
