Cammy is using an inference if she says "Typically, students register by October,"

An information source can be defined as a system or medium through which information, knowledge and ideas may be gotten and used by an individual. It can either be a primary or secondary source of information.

The source options (channels) for an information are television, radio, web, newspapers, journals, magazines, etc.

In English language, an inference can be defined as an act or process which typically involves deducing the meaning or generating an idea (message) from an information source through induction. Thus, you make an inference by using the information you previously have about a specific subject or issue.

In this scenario, Cammy is using an inference because she was able to state the particular month (October) when students typically register.

In conclusion, based on past information that are available to Cammy, she's able to infer the particular time students register i.e October.
