Pick any two variables that you feel may be related and estimate
what you think the strength of the correlation coefficient would be
for those two variables. In your response, estimate the value of r.
For example, specify a strong (.7 to .9), medium (.4 to .6), or low
(0 to .3) value for r. The value of the coefficient can be positive
or negative. For example, consider an increase in police patrols in
a neighborhood and the number of burglaries that occur in that
neighborhood. I would say that would be a strong inverse
relationship with an R-value of -0.8; as one (patrols) increases,
the other (burglary rate) goes down. Describe the factors that you
think would contribute to why the variables would have the
relationship that you estimate it to be.

Think of a problem dealing with two possibly related variables
(Y and X) that you may be interested in. Share your problem and
discuss why a regression analysis could be appropriate for this
problem.
Specifically, what statistical questions are you asking? Why
would you want to predict the value of Y? What if you wanted to
predict a value of Y that’s beyond the highest value of X (for
example if X is time and you want to forecast Y...

Think of a problem dealing with two variables (Y and X) that you
may be interested in. Share your problem and discuss why a
regression analysis could be appropriate for this problem.
Specifically, what statistical questions are you asking? You should
describe the data collection process that you are proposing but you
do not need to collect any data.

Pick two goods you think floors should be placed on and two goods
that you think ceilings should be placed on. Identify those 4 goods
and why you chose them. What problems might occur in the
marketplace based on your choices? What benefits might there be? Do
NOT chose goods listed in the textbook.

a. Describe how you might separate them from each other using
techniques that you have read about, are using in lab, or that you
have used elsewhere. (ex. size exclusion chromatography)
b. Indicate how you could determine that you had successfully
separated them.

Pick any organism (other than humans and domesticated animals)
that you are familiar with. It may be a plant, insect, animal or
bacteria. Carefully think about the organism’s environment. Think
about the organism’s life cycle and day to day life. Write a story
about your organism’s life. What kind of competition does your
organism experience? How is your organism uniquely adapted to
compete? What other ways could your organism adapt to become more
fit?
You must include any five of...
