Spam Spam filters try to sort your e-mails, deciding whichare real messages and which are unwanted. One methodused is a point system. The filter reads each incominge-mail and assigns points to the sender, the subject, keywords in the message, and so on. The higher the point total,the more likely it is that the message is unwanted. The filterhas a cutoff value for the point total; any message ratedlower than that cutoff passes through to your inbox, and therest, suspected to be spam, are diverted to the junk mailbox.We can think of the filter’s decision as a hypothesistest. The null hypothesis is that the e-mail is a real messageand should go to your inbox. A higher point total provides evidence that the message may be spam; when there’s suf-ficient evidence, the filter rejects the null, classifying the message as junk. This usually works pretty well, but, ofcourse, sometimes the filter makes a mistake.a) When the filter allows spam to slip through into yourinbox, which kind of error is…
