Every year, Christmas Island in the Pacific is overrun with over 120 million red crabs (Gecarcoidea natalis) moving across land between their breeding ground and habitat and towards the water to spawn.
Write and explain at least two alternate hypotheses
for each of the following questions, and propose research to test
your hypothesis. For your proposed research for each section,
explain whether your work will be experimental, correlational, or
conceptual and be sure to note what the strengths and weaknesses of
your approach might be. Make sure that you explain you logic
well.
a. What might be the adaptive benefits of everyone
migrating at the same time? (think about what happens to
individuals that miss the event, or travel separately)
b. In this species males leave their burrows and
arrive at the beach a couple of days before the females. Why might
they do this?
c. How do they coordinate such that they migrate at
the same time? (what type of cues might say it is time to leave,
what physiological mechanisms might be at play?)
d. How do the crabs know where to go? (think about
navigation and whether components might be learned or
inherited).

Imagine that you are putting together a presentation that will use that data to address questions about your topic – for example, questions about risk factors, demographics, etc. List five questions that your data could address, and explain which kinds of charts and graphs would be most effective to display the relevant data for each question. Be sure to explain your answers in detail....

Answer the following questions thoroughly. Use correct grammar and punctuation.
1) A student observes the following spinner and claims that the color red has the highest probability of appearing, since there are two red areas on the spinner. What is your reply? Your answers should include facts, rules, any definitions necessary to explain why the student is correct or incorrect.
2) In class, an experiment of flipping a coin is performed.
Pretend that you are introducing the concept of probability and introducing the terms 1) experiment, 2) outcomes, 3)sample space, 4) theoretical probability, and 5) empirical probability. Explain these terms, as if you were speaking to a 5th grade class, as if they knew nothing about probability. You will need to tell the class what each term , 1-5, is represented by in this particular example. Use correct grammar and punctuation.

Explain to a friend what you have learned about documentation and evidence. Be sure to detail why we need it and how we get it. Do not get too technical; they do not understand accounting or auditing. You may use a combination of formal terms, examples, and resources to support your answer.
