2.) No, because biased in research leads to unrepresentative outcomes as the estimates is predisposed to the left or to the right of the true values.
3.) Yes. Since the selection of shift has an equal probability of being chosen.
4.) No. The probability that the sample accurately reflects the efficiency of the workers, the standard should be 95%.
Are you meaning something like 1 to 50= 2 to 100 or something like 1 to 50, 1:50,1/50 they all r the same??
Answer:
![A=(9/64)\pi\ units^{2}](https://tex.z-dn.net/?f=A%3D%289%2F64%29%5Cpi%5C%20units%5E%7B2%7D)
Step-by-step explanation:
The area of a circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
we have
----> the radius is half the diameter
substitute
![A=\pi (3/8)^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%283%2F8%29%5E%7B2%7D)
![A=(9/64)\pi\ units^{2}](https://tex.z-dn.net/?f=A%3D%289%2F64%29%5Cpi%5C%20units%5E%7B2%7D)
