Spam filters in an email program are similar to hypothesis tests in that there are two possible decisions and two possible realities and therefore two kinds of errors that can be made. The hypotheses can be considered as: H0: Incoming email message is legitimate. Ha: Incoming email message is spam. Suppose an incoming legitimate message is flagged by the spam filter and sent to the spam folder. What type of error did the spam filter make?

The spam filter made a type I error.

Step-by-step explanation:

A type I error is the mistake of rejecting the null hypothesis when it is true.

The incoming message was legitimate (null hypothesis) but the spam filter made a mistake to have rejected it and sent it to the spam folder.
