Answer

Explanation:

Step1: Calculate the proportion in the sample

The proportion of infected - computers in the sample is $\frac{6}{40}$.

Step2: Convert the proportion to a percentage

To convert $\frac{6}{40}$ to a percentage, we use the formula $\text{Percentage}=\frac{6}{40}\times100%$. $\frac{6}{40}\times100% = 0.15\times100%=15%$.

Answer:

15%
