John believes that carpenter ants are, on average, angrier than fire ants. A sample of 40 carpenter ants gives an average anger level of 11.21 with a standard deviation of 3.11. The sample of 25 fire ants gives an average anger level of 9.27 with a standard deviation of 2. Complete the two-sample (difference of means) hypothesis test.

Chapter 4, Section 3, Exercise 116 Lizards and Invasive Fire Ants This exercise addresses lizard behavior in response to fire ants. The red imported fire ant, Solenopsis invicta, is native to South America, but has an expansive invasive range, including much of the southern United States (invasion of this ant is predicted to go global). In the United States, these ants occupy similar habitats as fence lizards. The ants eat the lizards and the lizards eat the ants, and in...
