Answer:
right the whole question
Step-by-step explanation:
if he sold 32 items this week last week he sold 20
The margin of error given the proportion can be found using the formula
![z* \sqrt{ \frac{p(1-p)}{n} }](https://tex.z-dn.net/?f=z%2A%20%5Csqrt%7B%20%5Cfrac%7Bp%281-p%29%7D%7Bn%7D%20%7D%20)
Where
![z*](https://tex.z-dn.net/?f=z%2A)
is the z-score of the confidence level
![p](https://tex.z-dn.net/?f=p)
is the sample proportion
![n](https://tex.z-dn.net/?f=n)
is the sample size
We have
![z*=2.58](https://tex.z-dn.net/?f=z%2A%3D2.58)
![p=0.38](https://tex.z-dn.net/?f=p%3D0.38)
![n=80](https://tex.z-dn.net/?f=n%3D80)
Plugging these values into the formula, we have:
![2.58 \sqrt{ \frac{0.38(1-0.38)}{80} } =0.14](https://tex.z-dn.net/?f=2.58%20%5Csqrt%7B%20%5Cfrac%7B0.38%281-0.38%29%7D%7B80%7D%20%7D%20%3D0.14)
The result 0.14 as percentage is 14%
Margin error is 38% ⁺/₋ 14%
