Bee hotels are human-made structures that provide nesting sites to cavity nesting bees and wasps. The logs are drilled with different drill bit diameters, ranging in size from 4 to 10.3 mm. Female bees mass-provision pollen in brood chambers and lay eggs on each individual pollen pack. Immature bees consume the pollen, pupate and emerge from the cavities as adults. The students wanted to know what factors associated with these human-made nests affect cavity-nest colonization. Students measured the number of holes colonized (occupied) by solitary bees and wasps in 14 wood logs. They also measured log size (width and length) and several other variables (see list below). Below are the experimental variables. The table below shows the results from the experiment

Experimental Variables:

Log #
# occupied holes
# unoccupied holes
Diameter of holes (mm)
Average depth of unoccupied holes (mm)
Average distance from one hole to another (mm)
Log length (mm)
Log width (mm)
Angle of holes
Does log have bark?
Color of occupied holes, dark or light?
Location of occupied holes in log (quadrant on face of log): NW, NE, SW, SE
Using the data provided in Table below, answer the following questions:

a. Write one hypothesis and one prediction for the experiment (based on the list of variables)

b. What were the experimental units?

c. What were the dependent and independent variables?

d. Using Table 2, summarize a component of the data in a way that will ease interpretation based on your hypotheses (hint: you can either make summary tables or produce graphs). You do not have to statistically analyze the data, but you may create graphs showing relationships between two or more variables. What do the results indicate?
