Does spam email affect everyone equally? In a preliminary study at the Axis Corporation, The Finance, Human Resource, and Operations departments were randomly sampled. Each person was asked to count the number of spam emai l messages received that day. The results are found below. Can we infer at the 2.5% significance level that the differing departments differ in the amount of spam they receive in their emails?
Finance 7 4 0 3 18
HR 5 9 12 16 10
Operations 12 4 5 18 15
