In a simple experiment, you are going out there to the duck
pond to seine out one redbreast sunfish at random, determine its
sex, and put it back in the pond and then, after 30 minutes, repeat
this process. Assuming that the sex ratio for redbreast in the pond
is 1:1, develop and plot the pmf of the random variable X, defined
as the number of females in the two fish observed.
Is the distribution of X symmetric or asymmetric?
Explain why the result in (a) was obtained.
Describe a simple experiment (at most 2-3 sentences) that you
would perform to determine whether the sex ratio is really
1:1.

if the calculated value of T is between c1 and c2 then we can
conclude that the sex ratio is 1:1. Otherwise not so.

Cobalt has spilled into a pond and our task is to precipitate it
out.
Your task is to choose a precipitation agent. It has been found
that the cobalt is in the +2 state. After consulting your handy
textbook, you see that the possible precipitants are carbonate,
sulfide and hydroxide ions. Remember that the pH of the pond is
already set.
Based on what you know about equilibria, write the pertinent
chemical reactions that would occur for each of the...
After Carrying out the Aspirin synthesis experiment, Suggest an
experiment or technique based on what you have learned in the last
few weeks to confirm the preparation of Aspirin. (Give full
details) Hint: You are provided with pure sample of
Aspirin
You are going to carry out a gastric lavage (stomach pump) in
order to try and get rid of the aspirin that has not yet been
absorbed. The procedure involves washing the organ with a solution
of a certain pH containing activated charcoal to bind the aspirin.
The pH of the stomach is typically around 2.0. Which of the
following do you think would be the most effective lavage? Hint:
think about the pH at which aspirin would cross the...

In a few sentences explain how you can perform and experiment to
find out if a circuit element is ohmic or nonohmic. What
measurements do you make and how do you decide, based on the
results of your measurements.

In a research laboratory you are doing an experiment on mice bone
to find out enzymatic activity. What would be the best way to
prepare your biopsy for this purpose.
Using a long rod that has length μ, you are going to lay out asquare plot in which the length of each side is μ. Thus thearea of the plot will be μ2. However, you do notknow the value of μ, so you decide to make n independentmeasurements X1, X2, ..., Xn ofthe length. Assume that each Xi has mean μ(unbiased measurements) and varianceσ2.a. Show that x 2 is not an unbiased estimator for μ2.b. For what value k is the...
In doing a real estate proforma, you often have to determine a
"terminal" (or "going-out") cap rate. Which of the following best
describes what this is?
a.
A rate of return you expect in the final year of ownership
b.
An after tax "final" return calculated at the end of your
proforma.
c.
An internal rate of the return over the expected ownership
period
d.
A rate used in conjunction with expected future cash flow to
derive a sales price
