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 15 of the PCs connected to the LAN, and finds that 9 are infected; use proportion to estimate the number of infected PCs if there are a total of 202 PCs connected to the LAN.
-------------
Let "x" be the number of infected PCs.
EQUATION:
x/202 = 9/15
x/202 = 3/5
x = 121 1/5
------------
Rounding down: x= 121
