Spam is the price we pay to be capable of easily communicating using e-mail. Does spam affect everyone equally? In a preliminary study, university professors, administrators, and students were randomly sampled. Each person was asked to count the number of spam messages received that day. The results follow: Professors Administrators Students 7 5 12 4 9 4 0 12 5 3 16 18 18 10 15 Can we infer at the 5% significance level that the differing university communities differ in the amount of spam they receive in their e-mails?
