Wooly Worm Conclusion
a. Degrees of freedom: 6
c. Chi-square value: 40.06
d. They do not indicate this because since we had a high chi-squared value, the selection of worms was not random.
e. Positive selection pressure: Shrek, Burt, Stringbean, Olive Garden
Negative selection pressure: Stripey, Eyelash, Shaggy
f. These results indicate that those with negative selection pressure will get picked off quickly, and those with positive selection pressure will survive longer.
g. Predatory birds will most likely be attracted to prey of brighter colors because they can be spotted more easily than other worms. Therefore, if a worms is a bright color or has distinguishable characteristics, they will most likely be a greater target to birds of prey.
h. The population would change in that the worms with negative selection pressure would be possibly wiped out and the community of worms would be reduced to only worms with positive selection pressure.
