Answer:
-3, -7
Step-by-step explanation:
either x + 3 = 0 --> x = -3
or x + 7 = 0 --> x = -7
Answer: 126
Step-by-step explanation:
As per given , we have
Prior Population proportion : ![p=\dfrac{1}{5}=0.2](https://tex.z-dn.net/?f=p%3D%5Cdfrac%7B1%7D%7B5%7D%3D0.2)
Significance level : ![\alpha=1-0.95=0.05](https://tex.z-dn.net/?f=%5Calpha%3D1-0.95%3D0.05)
Critical value for 95% confidence interval (using the z-value table) = ![z_{\alpha/2}=1.96](https://tex.z-dn.net/?f=z_%7B%5Calpha%2F2%7D%3D1.96)
Margin of error (maximum error): ![E=7\%=0.07](https://tex.z-dn.net/?f=E%3D7%5C%25%3D0.07)
Formula to find the sample size :
![n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2\\\\ n=0.20(1-0.20)(\dfrac{1.96}{0.07})^2\\\\ n=125.44\approx126](https://tex.z-dn.net/?f=n%3Dp%281-p%29%28%5Cdfrac%7Bz_%7B%5Calpha%2F2%7D%7D%7BE%7D%29%5E2%5C%5C%5C%5C%20n%3D0.20%281-0.20%29%28%5Cdfrac%7B1.96%7D%7B0.07%7D%29%5E2%5C%5C%5C%5C%20n%3D125.44%5Capprox126)
Therefore , the required minimum sample size = 126
