Data description: This data measures the quantity of lady beetles collected on yellow sticky traps placed in soybean plots receiving attractive baits. Each plot received 1 bait type (categorical, 2 treatment levels = Bait A and Bait B) and 1 bait dispenser type (categorical, 2 treatment levels = Slow release or Fast release), applied in a factorial manner. Each treatment combination was replicated 5 times, for a total of 20 independent replicates. Yellow sticky traps were collected after 2 weeks, and the number of adult lady beetles was recorded per species. Two species were captured, Harmonia axyridis (h_axy) and Coccinella septempunctata (c_sept), the counts of each are the two dependent variables for this study. For this study, assume that each plot was far enough apart to be independent.

3. Based on your cursory exploration of the dataset, answer the following questions. In each of your responses, cite/reference the specific information (i.e. figures/tables) that you used to reach your conclusion. [1 mark each]

a. Does the mean number of Harmonia axyridis (h_axy) captured per bait type appear to differ?
