Given Information:
Sample size = n = 40
sample proportion = p = 35% = 0.35
Required Information:
standard deviation of sample proportion = σ
Answer:
standard deviation of sample proportion = σ = 0.075
Step-by-step explanation:
Check if the condition np ≥ 10 or n(1 - p) ≥ 10 is satisfied
np ≥ 10
40*0.35 ≥ 10
14 ≥ 10 satisfied
n(1 - p) ≥ 10
40(1 - 0.35) ≥ 10
26 ≥ 10 satisfied
Which means that distribution of sample proportion will have a mean closer to the population proportion.
The standard deviation for sample proportion is given by
![\sigma = \sqrt{\frac{p(1-p)}{n}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%7D)
![\sigma = \sqrt{\frac{0.35(1-0.35)}{40}}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B%5Cfrac%7B0.35%281-0.35%29%7D%7B40%7D%7D)
![\sigma = 0.075](https://tex.z-dn.net/?f=%5Csigma%20%3D%200.075)
Therefore, the standard deviation for the sampling distribution of the sample proportions is 0.075.
To find surface area you must find the area of the top, area of the bottom, area of the front side, area of the back side, area of the left side and area of the right side. Then you would add them together.
