Answer:

Step-by-step explanation:
It is known that the mean and standard deviation of the sampling distribution of the sample proportion(
) are represented as follows:-

, where p= Population proportion and n = sample size.
Let p denote the proportion of blue chips.
According to the information provided, we have
p= 0.275
n= 5
Thus, the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 will be:

Therefore, you will have the mean and standard deviation for the sample proportion of blue chips for samples of size 5:

<span><span>Center coordinates: (x0, y0, z0)</span></span> and radius r.
<span>The equation of the sphere is:</span>
<span>(x - x0)^2 + (y - y0)^2 + (z - z0)^2 = r^2</span>
To calculate the area, simply multiply 5 by 4, resulting in 20.
