Answer:

15%

Step-by-step explanation:

The population proportion can be estimated as the sample proportion.

6 / 40 = 0.15

Approximately 15% of the computers have viruses.

Answer: Hence, there are 15% of computers have viruses.

Step-by-step explanation:

Since we have given that

Total computers in an office = 500

Number of computers to be inspected = 40

Number of computers had viruses = 6

We need to find the percentage of the computers in the building that have viruses.

So, Percentage of computers in the buildings have viruses is given by

[tex]\dfrac{6}{40}\times 100\\\\=\dfrac{600}{40}\\\\=15\%[/tex]

Hence, there are 15% of computers have viruses.
