Answer: 47
Step-by-step explanation:
Given : Margin of error : ![E=0.12](https://tex.z-dn.net/?f=E%3D0.12)
Significance level : ![\alpha: 1-0.90=0.10](https://tex.z-dn.net/?f=%5Calpha%3A%201-0.90%3D0.10)
Critical value : ![z_{\alpha/2}=1.645](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.645)
The formula to find the sample size when no prior proportion exists is given by :-
![n=0.25(\dfrac{z_{\alpha/2}}{E})^2](https://tex.z-dn.net/?f=n%3D0.25%28%5Cdfrac%7Bz_%7B%5Calpha%2F2%7D%7D%7BE%7D%29%5E2)
i.e. ![n=0.25(\dfrac{1.645}{0.12})^2](https://tex.z-dn.net/?f=n%3D0.25%28%5Cdfrac%7B1.645%7D%7B0.12%7D%29%5E2)
![=46.9796006944\approx47](https://tex.z-dn.net/?f=%3D46.9796006944%5Capprox47)
Hence, the minimum required sample size =47

Answer:
1/2
Step-by-step explanation:
When given two points, we can find the slope by
m = (y2-y1)/(x2-x1)
= (1-0)/(-3- -5)
= (1-0) / (-3+5)
= 1/2
