Answer:
(14.7 , 16.9)
Step-by-step explanation:
it is given that
tons
σ=3.8 tons
n=49
at 95% confidence level α=1-.95=0.05
![z_\frac{\alpha }{2}=z_\frac{0.05}{2}=z_{0.025}\\](https://tex.z-dn.net/?f=z_%5Cfrac%7B%5Calpha%20%7D%7B2%7D%3Dz_%5Cfrac%7B0.05%7D%7B2%7D%3Dz_%7B0.025%7D%5C%5C)
=1.96 ( from the standard table)
at 95% confidence level the coefficient interval for μ is
![15.8\pm 1.1](https://tex.z-dn.net/?f=15.8%5Cpm%201.1)
(14.7, 16.9)

Answer:
Step-by-step explanation:
<h3>Solution</h3>
- 6 - 2n - 5< -11
- 1 - 2n < -11
- -2n < -12
- n > 6
<h3>Check</h3>
- n = 10
- 6 - 2*10 - 5 < -11
- 6 - 20 - 5 < -11
- -19 < -11
Graph is the line segment of the right from point 6 not including 6
4,567
2,000
................
2,567
The distance between these two points will be the radius of the circle.
8 - 5 = 3
So the radius is 3.
C = 2πr
C = 2π(3)
C <span>≈ 18.8</span>
