Write a 3-page paper on a current event article that discusses restrictions on freedoms by a totalitarian state or an article on ethnic conflict within a nation.

Summarize the article and explain why this issue is important to the global community. What outside influences might help change this issue? How? Is the article neutral? Why or why not?

Be sure to include a scanned copy of the article in your submission in addition to citations. Articles may not be more than one month old.

The following data is representative of that reported in an article with x = burner-area liberation rate (MBtu/hr-ft2) and y = NOx emission rate (ppm): x 100 125 125 150 150 200 200 250 250 300 300 350 400 400 y 150 140 170 210 180 320 280 400 420 440 400 590 620 680 (a) Does the simple linear regression model specify a useful relationship between the two rates? Use the appropriate test procedure to obtain information about the P-value, and then reach a conclusion at significance level 0.01. State the appropriate null and alternative hypotheses. H0: β1 = 0 Ha: β1 > 0 H0: β1 = 0 Ha: β1 < 0 H0: β1 = 0 Ha: β1 ≠ 0 H0: β1 ≠ 0 Ha: β1 = 0 Correct: Your answer is correct. Calculate the test statistic and determine the P-value. (Round your test statistic to two decimal places and your P-value to three decimal places.) t = P-value = State the conclusion in the problem context. Reject H0. There is evidence that the model is useful. Reject H0. There is no evidence that the model is useful. Fail to reject H0. There is no evidence that the model is useful. Fail to reject H0. There is evidence that the model is useful. (b) Compute a 95% CI for the expected change in emission rate associated with a 10 MBtu/hr-ft2 increase in liberation rate. (Round your answers to two decimal places.) , ppm You may need to use the appropriate table in the Appendix of Tables to answer this question.

(1) Explain the difference between simple distillation and fractional distillation. Which method was more effective at separating the components of your mixtures? How were you able to determine a difference if one was present? Why was there a difference between the two methods if one was present?

(2) Explain in some detail (words and pictures) how each of the three following variables would affect the retention times of a mixture of ethylene glycol and 1-bromobutane

(a) Flow rate of helium carrier gas

(b) Interaction between compounds and stationary phase

Simple distillation: Separate a two-component organic mixture (1:1, tetrahydrofuran and 1-propanol)

Fractional distillation: Separate a two-component organic mixture (1:1 unknown composition)

Various studies indicate that approximately 9% of the world's population is left handed. You think this number is actually higher. You take an SRS of 221 people and find that 22 of them are left handed. Test your claim at the 5% significance level.

Part a: State your null and alternative hypotheses.

Part b: Sketch the rejection region.

Part c: Calculate the test statistic. Plot this value in your sketch in part b.

Part d: Determine the P-value for your test.

Part e: State your conclusion clearly in complete sentences.

thank you and use R if possible!

You are the finance manager of a company and currently your company has $100 million in cash that will not be needed for a few more weeks. You are thinking about arbitrage opportunities using Euro and GBP in order to put the cash reserves into use and hopefully earn more money for your company. You have to make a decision about details of your arbitrage with regard to which currency to buy in which order. Check exchange rates, find current rates for USD, Euro, and GBP, and share the details of your arbitrage plan with your CEO. Is it poosible to find an arbitrage trade to generate some profits (assume you will have no trading costs)? If so, what should be the order of your transactions in order to make a profit from this arbitrage operations?

I received a response stating "need enough knowledge" and about "exchange rates". I am not sure what that means, please elaborate instead of 2-3 word responses.

1) why is the difference between an avoidable delay and an unavoidable delay important to a contractor? 2) What is the difference between a calender day and a working day? 3) Why would it be necessary and desirable to perform resource leveling for a construction schedule? 4) In which parts of a schedule should a contractor share the most detail with an owner? 5) As a contractor, what concern would you have regard cost and productivity if an owner directed you to use overtime to catch up on a scehdule?

The hypothesis being tested is:

H0: Plain M&Ms follow the stated distribution

Ha: Plain M&Ms does not follow the stated distribution

The p-value is 0.0000.

Since the p-value (0.0000) is less than the significance level (0.05), we can reject the null hypothesis.

Therefore, we can conclude that Plain M&Ms does not follow the stated distribution.

A different significance level would not have changed the conclusion.

3. Use the distribution below to test that Halloween Skittles follow the stated distribution. Discuss your choice of significance level. Would a different significance level have changed your conclusion?
Skittles states the following distribution:
Red = 18%, Orange = 22%, Green = 17%, Blue = 20%, Purple = 22%, Other (Zombie color) = 1%
