Answer:
The standard deviation for the sample mean distribution=0.603
Step-by-step explanation:
We are given that
Mean,![\mu=63](https://tex.z-dn.net/?f=%5Cmu%3D63)
Standard deviation,![\sigma=4](https://tex.z-dn.net/?f=%5Csigma%3D4)
n=44
We have to find the standard deviation for the sample mean distribution using Central Limit Theorem for Means.
Standard deviation for the sample mean distribution
![\sigma_x=\frac{\sigma}{\sqrt{n}}](https://tex.z-dn.net/?f=%5Csigma_x%3D%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D)
Using the formula
![\sigma_x=\frac{4}{\sqrt{44}}](https://tex.z-dn.net/?f=%5Csigma_x%3D%5Cfrac%7B4%7D%7B%5Csqrt%7B44%7D%7D)
![\sigma_x=\frac{4}{\sqrt{2\times 2\times 11}}](https://tex.z-dn.net/?f=%5Csigma_x%3D%5Cfrac%7B4%7D%7B%5Csqrt%7B2%5Ctimes%202%5Ctimes%2011%7D%7D)
![\sigma_x=\frac{4}{2\sqrt{11}}](https://tex.z-dn.net/?f=%5Csigma_x%3D%5Cfrac%7B4%7D%7B2%5Csqrt%7B11%7D%7D)
![\sigma_x=\frac{2}{\sqrt{11}}](https://tex.z-dn.net/?f=%5Csigma_x%3D%5Cfrac%7B2%7D%7B%5Csqrt%7B11%7D%7D)
![\sigma_x=0.603](https://tex.z-dn.net/?f=%5Csigma_x%3D0.603)
Hence, the standard deviation for the sample mean distribution=0.603

Answer: give me brainliest
Step-by-step explanation:
ax+by=a-b
ax=a-b-by
x=a-b-by/a←
bx-ay=a+b
substituting
b(a-b-by/a)-ay=a+b
ab-b²-b²y/a-ay=a+b
ab-b²-b²y-a²y/a=a+b
ab-b²-(b²+a²)y=a²+ab
-(b²+a²)y=a²+ab-ab+b²
(b²+a²)y=-(a²+b²)
y=-(a²+b²)/a²+b²
y=-1←
substituting value of y
x=a-b-b(-1)/a
x=a-b+b/a
x=a/a
x=1
