Wooly Worm
1. The degrees of freedom used in the exercise was 6.
2. (don't do)
3. The calculated chi-square value is 40.06.
4. Results indicate it was not chance that caused the unequal numbers of captured wooly worm phenotypes. Most worms were found in one designated area.
5. The colors of worms subjected to a positive selection pressure was the Shaggy worm. They were picked the least despite being colorful. The worms subjected to a negative selection pressure were the Shrek and Burt worms. They were selected the most despite them being green and being able to blend with the surrounding grass and trees.
6. Over time the population of the shrek and burt worms would decrease.
7. In nature worms would most likely be chosen by predators for their colorful bright colors (like the eyelash worm).
8. If the grounds remained unchanged then the populations would grow with the colorful populations most likely dying off. The worms could maybe migrate as well and mix up.

Parking Lot Species Diversity
Post-lab Question
1. Identify the parking lot that was the most diverse. Based on your observations during the lab, explain why your
prediction in question #1 of the pre-lab was supported or not supported.
The parking lot that was the most diverse was the student parking lot.
2. List the single most abundant species in each set of data, and write a plausible explanation to explain why these are
the most abundant species.
In the student parking lot the most abundant species was Chevy. In the teacher parking lot the most abundant species was Ford (it beat Chevy by 2).
3. Determine the maximum and minimum values for the Shannon Diversity Index in the parking lot you surveyed.
4. If you conducted this lab in a shopping mall parking lot, predict whether the Shannon Diversity Index would be high or
low, and how it would compare to the school parking lots.
The Shannon Diversity Index would be higher than the school parking lots because there would be a greater number of cars and a greater variety.
5. If you conducted this lab at a new car dealership, predict whether the Shannon Diversity Index would be high or low,
and how it would compare to the school parking lots.
It would be lower because typically a new car dealership would sell one brand of cars.

Data Snapshots
Population Pyramids
The population is stable. This is most likely because of steady jobs and good environments to raise families.
There is a stable population. This could be because of the job opportunities and the Universities in the area.
The pyramid shows slow expansion as well as a decline in population. The area may be more suited to families than single individuals.
There was a sharp expansion then the population became stable. There may have been an increase in jobs which lead to a steady flow of families moving into the area.
The population is expanding rapidly but then declining. There could have been an increase in college students who decided to settle down in the city but are not looking to start families at the moment.
There was rapid expansion then a sharp decline in the population. This could be due to not many people were looking to start a family in the city.
Monterey's population is stable. This could be because the cost of living in the area fits certain socio-economic groups and there is a college within the city.
