You are the Colonel of the Maryland State Police, and you are concerned about drinking among state troopers.  You take a random sample of 150 police offers and find that the median number of drinks per week is 2 and the mean number of drinks per week is 4.7 with a standard deviation of 8.

1. Construct a 90% confidence interval around the appropriate point estimate. Interpret your results.

2. Construct a 93% confidence interval around your point estimate.  Interpret your results.  Why did the interval change?

3. What would happen if we increased our confidence level to 99% (You do not need to recalculate the CI)?

Use the following information to answer the questions.

a. What is the expected return of each asset?

b. What is the variance of each asset?

c. what is the Standard deviation of each asset?

Use the following information to answer the questions.

Disorder At-a-Glance STEP 1: Pick one of the disorders you read about in this module and learn more about it in order to make a “At-a-Glance” page with details about the disorder. Visit the National Institute of Mental Health and search for the disorder, read through the information, then scroll to the section on “Research and Statistics” or “Journal Articles or Reports” to find helpful links to outside information. Look elsewhere as well for details about the prevalence, signs, symptoms, details, and research related to the disorder. Keep track of all of your sources as you investigate. STEP 2: In a format of your choosing (Microsoft Word, PowerPoint, etc.), create a 1 page visual that includes the following information about the disorder: Description Prevalence Causes and Risk Factors Recent Research (referencing at least 2 research articles) Either as a footnote on the same page, or on a separate page, include the citations in APA format

Hi I am confused a little about equations for constructive and destructive interference and also about the difference in equations for diffraction and interference and also what equations we use for young's single slit experiment and double slit experiment.Can you please explain the difference??

1. The output of an economy is characterized by a Cobb-Douglas production function with constant return to scale and an output elasticity with respect to capital equal to 0.3. Also given are the following parameters: 30% saving rate, 5% depreciation rate, 2% population growth rate, and the technology factor is 2.

a). Find the capital-labour ratio, and also the output, consumption and investment on a per capita basis in the steady state equilibrium.

b). Is a government policy that raises the saving rate to 40% socially desirable? Explain your answer with reference to a comparison of this new steady state equilibrium and the initial steady state equilibrium in a) above.

c). If the initial capital-labour ratio is 30, is the economy operating efficiently in the sense that welfare cannot be improved? Explain concisely. What if the initial capital-labour ratio is 15? Again explain concisely.
