Question 55313: A new virus is released on the internet; the administrator of a department's Local Area Network ( LAN) is given five minutes by a manager to estimate the impact. The administrator samples 12 of the PCs connected to the LAN, and finds that 7 are infected; use proportion to estimate the number of infected PCs if there are a total of 117 PCs connected to the LAN.

Let "x" be the number infected out of 117; then
x/117 = 7/12
x = 117(7/12)
x= 68.25
Approximately 68 out of the 117 are infected.
Cheers,
Stan H.
