Animal Rights Law and Politics: What might have allowed the Sierra Club to have standing in Sierra Club v. Morton?

Case: Sierra Club v. Morton, 405 U.S. 727 (1972)

1. An experiment is to be conducted to assess effect of temperature on the
amount of impurities removed by using water samples contaminated with the
same level of impurity. Six samples are to be tested at each of 5 temperatures
and the amount of impurities removed in each sample recorded.
(a) What is the response variable?
(b) What is the factor of interest?
(c) What are the levels of this factor?
(d) What experimental design is suitable?
(e) Describe how the 30 measurements should be made.
(f) If the samples did not have the same level of impurity, what response variable
will be appropriate?
(g) Why is using samples with the same level of impurity better?
(h) Write the appropriate model for this experiment. Define the terms in the model
with reference to this experiment.

Two separate experiments -- double-slit and diffraction grating -- use a 400-nm electromagnetic wave. In both experiments, a long, flat wall where the results are seen is located 2.00-m across from the slits/grating. The slit separation for the double-slit experiment is 0.20mm. The diffraction grating has 1200 lines per mm.

a. Calculate the distance between the first and second bright spots below the center line for each experiment. Compare your answer for each experiment and explain how the pattern created on the screen by the two experiments would differ.

b. If the slit-width is roughly the same for both, which pattern would have a brighter central maximum? Why?

You are doing an EMSA experiment. The DNA sequence you study is about 1000bp long and contains the first two exons of a protein coding gene. You run your DNA alone on the gel for 1 hour at 72 volts and you notice that the DNA fragment matches the 1000bp marker in the DNA ladder, which is to be expected. You then start adding different transcription factors to your DNA sample and run the EMSA experiment to see which one would bind to your DNA. After adding 10 different transcription factor proteins to your DNA sample and doing the EMSA experiment you see that none of them changes the mobility of you DNA fragment. Explain this observation.

1. When we experiment, we always want to think about sources of experimental uncertainty. In the lab "Measurement and Uncertainty" you learned about random errors and systematic errors. Let's think about some potential sources of uncertainty in this experiment.

   If the uncertainty is random, fill in R. If it is systematic, fill in S.

   In every trial, a student holds the picket fence so that it is tilted slightly to the left as it drops through the photogate.

   In the course of the experiment, the student holds the picket fence pretty close to vertical, but some times there is a slight tilt to either the left or right.

   One student group cannot find their picket fence. The decide to just drop a tennis ball through the photogate instead.

As we have seen in class, hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following:

1. A detailed discussion of your experimental design.
2. How is randomization used in your sampling or assignment strategy?
3. The type of inferential test utilized in your experiment.
4. A formal statement of the null and alternative hypothesis for your test.
5. A confidence interval for estimating the parameter in your test.
6. An interpretation of your p-value and confidence interval, including what they mean in context of your experimental design

The following is information for Palmer Co.

  
Use the above information to compute inventory turnover for 2017 and 2016, and its days' sales in inventory at December 31, 2017 and 2016.

Question 4 .

1.     The balance sheet for Colt Corp. provided the following summarized pretax data:

Year 2015            Year 2016

            Deferred tax liability                $376,000            $248,000

Tax expense as reported on the 2016 Income Statement was $493,000.

Calculate the amount of income taxes payable for 2016?

As a long-term investment, Bravo Company decided to purchase stock in Zulu Corporation. Bravo purchased 10,000 shares for a 10 percent ownership share at a cost of $10 per share on January 1, 2016. Zulu Corporation's net income in 2016 was $25,000, and they paid total dividends of $10,000. At the end of 2016, the Dow Jones market price for that Zulu stock was $12 per share. Based on this information, $__________ should be reported on the balance sheet for this investment on December 31, 2016

The following information for Vision Company is given:

1. Calculate the Accounts Receivable Turnover, Inventory Turnover and Day’s Sales in Inventory for 2016.
