Your paper should:

• Discuss the technical aspects of your topic in general terms.
• Discuss the public policy debates relevant to the topic you choose. This section should cover arguments that are in favor of and opposed to the use of the techniques or products.
• Express your personal opinion regarding the importance of the topic and the validity of the pro and con arguments.

Show all work for credit, including calculations and complete parts a)-c) Find all variables( SE, z or t, P-value, p hat, etc)

2) In 1994 I surveyed European and Asian new car owners one year after purchase about consumer satisfaction with the tread war life of their OEM tires to see if they would repurchase the same tire. Of 450 randomly selected Asian car owners, 342 owners said they would buy the same tires again. Of 360 randomly selected car owners, 252 said they would buy again. Use larger proportion p̂1.

a) State the conditions and verify they are met.

b) Find the indicated value for a 95% confidence interval of the difference in consumer satisfaction. Interpret your results.

c) Now perform an appropriate hypothesis test, and state your conclusion.

1.True/False. Explain.

(a)The normal is a right skewed distribution.____________________________________________________________________________________________________________________

_________________

(b)If a normal distribution is described by X ~ N(60, 5), then the median for this distribution is 60.___________________________________________________________________________

___________________________________________________________________

(c)For a normal distribution when you decrease the standard deviation, the curve becomes more flatter._____________________________________________________________________

2.Jerome averages 16 points a game with a standard deviation of four points. Fill in the blanks.

(a)ThenX~N(____,____).

(b)Suppose Jerome scores ten points in a game.Then the z–value for Jerome’s score is _________.

(c)This score tells you that x= 10 is _________ standard deviations to the ______(right or left) of the mean______(What is the mean?).

3.In 2012, 1,664,479 students took the SAT exam. The distribution of scores in the verbal section of the SATwas normal and had a meanμ= 496 and a standard deviationσ= 114. Let X= a SAT exam verbal section score of a student in 2012. ThenX~N(496, 114).

(a)Find the z-score(z1)for first student ,x1= 325 and also find the z-score(z2) fora second student x2= 366.21.z1= ________z2= ________

(b)Interpret each z-score. What can you say about x1= 325 and x2= 366.21 as they compare to their respective means and standard deviations?

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. A simple random sample of 25 filtered 100 mm cigarettes is​ obtained, and the tar content of each cigarette is measured. The sample has a mean of 18.8 mg and a standard deviation of 3.64 mg. Use a 0.05 significance level to test the claim that the mean tar content of filtered 100 mm cigarettes is less than 21.1 mg, which is the mean for unfiltered king size cigarettes. What do the results​ suggest, if​ anything, about the effectiveness of the​ filters?

What are the​ hypotheses?

Identify the test statistic.​(Round to three decimal places as​ needed.)

Identify the​ P-value.

The​ P-value is(Round to four decimal places as​ needed.)

State the final conclusion that addresses the original claim.

What do the results​ suggest, if​ anything, about the effectiveness of the​ filters?

This week we will look at the test for goodness of fit. In order to complete this discussion board, you will need a small bag of plain m&m’s.   M&m’s have six colors, listed below. The Mars Candy Company has published the percentage of each color that we should see in any given bag of m&m’s. We are going to determine if our purchases m&m’s are significantly different from what we should expect.

Our Null Hypothesis is that our percentages will match those provided by the company.

Our Alternate Hypothesis is that our percentages will not match those provided by the company.

Step 2:

Average your information with the information from two other students (three students total). This information is the OBSERVED data.

Observed data to be averaged:

• Color	Blue	Orange	Green	Yellow	Red	Brown	Total
  Number of M&M's	5	16	19	5	4	6	55
  Percent of Total	9%	29%	35%	9%	7%	11%	100%

  Color	Blue	Orange	Green	Yellow	Red	Brown	Total
  # of M&Ms	24	22	27	13	7	10	103
  % of Total	23%	21%	26%	13%	7%	10%	100%

• Color	Blue	Orange	Green	Yellow	Red	Brown	Total
  Number of m&m’s	13	5	3	10	9	5	45
  Percent of Total	29%	12%	7%	21%	20%	12%	100%

The EXPECTED data is published by the Mars Candy Company and is listed below:

Calculate the chi-square statistic using the formula on page 656 in your book, or use your calculator.

Then using a 0.05 level of significance and 5 degrees of freedom (because there are 6 colors), determine if we reject our Null Hypothesis or not.  

Glass Science -- Stress Relaxation : please show calculation in detail or with explanation:

1] a) Show, by calculation, how much time is required to relax 90% of the stress in a glass at the annealing point; the initial stress is 300 MPa, the temperature is 535C, the elastic modulus is 55 MPa, the shear modulus is 10 GPa and Poisson’s ratio is 0.3

b) What about at the strain point ?

c) What about at the softening point where tempering is often initiated ?

*You should understand how these kinetics play a role in annealing, tempering and glass/metal/ceramic sealing.

managerial accounting

This week you will continue working on creating a Business Plan for a new health care organization. Please read the requirements of this discussion board carefully as it varies from our usual format.

ge 312 of the eText explains that the following items are addressed in the Income Statement Assumptions section of a business plan:

• Revenue type/Revenue source(s)
• Revenue amount (e.g., as determined based on per patient, per visit, per month, per grant amount)
• Labor expenses
• Supply expenses
• Cost of drug or device expenses (if applicable)
• Equipment expenses
• Space occupancy expenses (e.g., rent, utilities)
• Overhead (insurance, etc.)

For your original post: (1) remind us about your new health care business, (2) address the values that you have determined/assumed for each of the items above, and (3) explain how you came to determine/assume the values for each of the items listed above.
