Answer:
5/8, 3/4, 7/8 this is the correct answer, just think of a ruler or measuring tape, hope this helps.
Step-by-step explanation:
From the question we are told that:
Sample size n=500
Know Virus infection r=8\%
The data can be represented in the Table below a
![\begin{tabular}{lllll}S/N & Reported & Not reported & Total \\Infected & 28 & 12 & 40 \\Not Infected & 28 & 36&460\\Total &122&378&500\\\end{table}](https://tex.z-dn.net/?f=%5Cbegin%7Btabular%7D%7Blllll%7DS%2FN%20%20%20%20%20%20%20%20%20%20%26%20Reported%20%26%20Not%20reported%20%26%20Total%20%5C%5CInfected%20%20%20%20%20%26%2028%20%20%20%20%20%20%20%26%2012%20%20%20%26%20%20%2040%20%20%20%5C%5CNot%20Infected%20%26%2028%20%20%20%20%20%20%20%26%2036%26460%5C%5CTotal%20%26122%26378%26500%5C%5C%5Cend%7Btable%7D)
Therefore the False Positive can be Mathematically represented as
![FP=\frac{94}{122}](https://tex.z-dn.net/?f=FP%3D%5Cfrac%7B94%7D%7B122%7D)
![FP=0.7705](https://tex.z-dn.net/?f=FP%3D0.7705)
![FP=77.05\%](https://tex.z-dn.net/?f=FP%3D77.05%5C%25)
In conclusion we can say that The magazine's review suggests Nate should use a different detection program because the probability that the scan result is a false positive is 77.05%
Therefore
Option B is correct
