Answer:
Researcher B
Step-by-step explanation:
Normally, when all other things being equal, we usually say that power is higher when the standard deviation is small than when it is large.
Now, from researcher A, standard deviation is 110 while from researcher B, standard deviation is 60.
We can see that the standard deviation for researcher B is smaller than that of researcher A.
Therefore, we can conclude that since the standard deviation for researcher B is lesser than that of researcher A, it means that Researcher B will have more power to detect an effect.

Answer:
D. The work shown above is correct, and ![y^5.\sqrt[4]{y^3}](https://tex.z-dn.net/?f=y%5E5.%5Csqrt%5B4%5D%7By%5E3%7D)
may not be simplified further.
Step-by-step explanation:
![\sqrt[4]{y^{23} } = \sqrt[4]{y^4 . y^4 . y^4.y^4.y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7By%5E%7B23%7D%20%7D%20%3D%20%5Csqrt%5B4%5D%7By%5E4%20.%20y%5E4%20.%20y%5E4.y%5E4.y%5E3%7D)
![\sqrt[4]{y^4. y^4.y^4. y^4.y^3} = y^5 . \sqrt[4]{y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7By%5E4.%20y%5E4.y%5E4.%20y%5E4.y%5E3%7D%20%3D%20y%5E5%20.%20%5Csqrt%5B4%5D%7By%5E3%7D)
When we simplify, we get
![\sqrt[4]{y^{23} } = y^5.\sqrt[4]{y^3}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7By%5E%7B23%7D%20%7D%20%3D%20y%5E5.%5Csqrt%5B4%5D%7By%5E3%7D)
The answer: D. The work shown above is correct, and ![y^5. \sqrt[4]{y^3}](https://tex.z-dn.net/?f=y%5E5.%20%5Csqrt%5B4%5D%7By%5E3%7D)
may not be simplified further.
Thank you.
