or, 15
. 5 ýard = 15 feet
The first choice is the correct answer.
If you are trying to circumscribe a circle around a triangle, you first draw the perpendicular bisectors of the triangle.
Then, you draw a circle with the center at their intersection. The radius of the circle will go out to any of the vertices of the circle.
Answer:
The value of the test statistic is t = 2.19.
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean
and standard deviation ![s = \sqrt{\frac{p(1-p)}{n}}](https://tex.z-dn.net/?f=s%20%3D%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
Our test statistic is:
![t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
In which X is the sample mean,
is the expected mean,
is the standard deviation and n is the size of the sample.
Sample of 1300 voters:
This means that ![n = 1300](https://tex.z-dn.net/?f=n%20%3D%201300)
Found that 45% of the residents favored construction.
This means that ![X = 0.45](https://tex.z-dn.net/?f=X%20%3D%200.45)
A political strategist wants to test the claim that the percentage of residents who favor construction is more than 42%.
This means that
, and by the Central Limit Theorem:
![\frac{\sigma}{\sqrt{n}} = s = \sqrt{\frac{0.42*0.58}{1300}} = 0.0137](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%20%3D%20s%20%3D%20%5Csqrt%7B%5Cfrac%7B0.42%2A0.58%7D%7B1300%7D%7D%20%3D%200.0137)
So, the test statistic is:
![t = \frac{X - \mu}{s}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7Bs%7D)
![t = \frac{0.45 - 0.42}{0.0137}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B0.45%20-%200.42%7D%7B0.0137%7D)
![t = 2.19](https://tex.z-dn.net/?f=t%20%3D%202.19)
The value of the test statistic is t = 2.19.
