In the last lab, we looked at a study to determine if the bait used in a trap (using scent, sugar, or a chemical) influenced the number of spruce moths that are caught in the trap. As a part of that study, researchers also wondered if the location of the trap in a tree (top branches, middle branches, lower branches, or at the ground) influenced the number of spruce moths caught in a trap. The researchers used 60 traps (all the same brand) and randomly assigned them to the different bait-location combinations. At the 5% significance level, can you conclude that Bait and Location interact in their effect on mean number of spruce moths caught? Use the Minitab output posted on Moodle and follow the steps below to answer this question. What is the response variable? List the factors (explanatory variables) and name the levels of each factor: Question 3 How many treatment groups are there?

Select one: 0 a. We cannot conclude there is an interaction effect between Bait and Location on the mean number of spruce moths caught in a trap, for this population model of spruce moths. O b. We can conclude that the Bait has no effect on the mean number of spruce moths caught in a trap, after allowing for Location, for this population model of spruce moths. O c. We can conclude that Bait has an effect on the mean number of spruce moths caught in a trap, after allowing for Location, for this population model of spruce moths. Q d. We cannot conclude that the Bait has an effect on the mean number of spruce moths caught in a trap, after allowing for Location, for this population model of spruce moths. At a 5% level of significance, can we conclude that the location of the trap has an effect on the mean number of spruce moths caught?
