Q1.Must write the hypotheses, analyze and state what your conclusions are and how you have drawn your conclusions. Also, state and check your assumptions.
Q2.explain the procedure of getting answers step-by-step.
Problem 1 : A research study was conducted to examine the clinical efficiency of a new antidepressant. Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a low dose of the drug, and a group that received a moderate dose of the drug. After four weeks of treatment, the patients completed the Back Depression Inventory. The higher the score, the more depressed the patient. The data is presented below. Compute the appropriate test.

Identify the following for the RST: What commodity sales are exempt? Are services taxed? What is the nominal rate? What are the brackets? Does your state (Arkansas) provide sales tax credits? In regard to selective excises: What selective excises are used? How are their bases defined? What rates apply?

Article:
The balance of the value of each group at the end of the taxable year is the total of the balance of the value of the group at the end of the previous taxable year after the depreciation deduction in accordance with this Article for the previous taxable year, and fifty percent (50%) of the cost base of assets in use added to the group in the current and previous taxable years after the deduction of fifty percent (50%) of the compensation received from the assets disposed of during the current and previous taxable years, provided that the balance does not become in the negative.

U.S. and Chinese GDP Growth in the Long Run. China is a country with a very high savings rate s, about 40%. The U.S. has a much lower savings rate, closer to 15%. (There are many reasons for this difference.) For this question, assume that the population growth rate n, technology growth rate g, depreciation rate δ, and production function f(k) in China are the same as in the U.S.
a) According to the full Solow growth model (with technology growth), what does this higher savings rate imply about the steady state of China’s output per effective worker relative to the U.S.? Draw a diagram to help illustrate your answer.
b) China’s GDP/person has been growing at about 8.2%/year for the past 25 years, while GDP/person in the U.S. has been growing closer to 2%/year. According to the full Solow growth model (with technology growth), how will the growth rate of China’s GDP/person compare to that of the U.S. once these two economies reach their steady states?
c) According to your analysis in part b, can China’s GDP/person continue to grow at its historical average rate of 8.2%/yr. for the indefinite future, while the U.S.’s steady-state growth rate of GDP/person is around 2%/yr.?

LetX1,...,Xnbe a random sample following Gamma(2,β) for some unknownparameterβ >0.
(a) What is the distribution of∑ni=1Xi? You don’t have to prove it.
(b) Apply WLLN on the sample mean ̄Xn=∑ni=1Xi/n. State the result.
(c) What does ̄X2n−3 log ̄Xnconverge to in probability? Explain.
(d) Apply CLT on ̄Xn. State the result.
(e) Assumeβ= 2, use normal approximation to calculate P(1≤∑ni=1Xi≤3).Express results in terms of the CDF ofN(0,1), i.e., Φ(·).
(f) What is the MLE ofβ?
(g) What is the MLE ofβ2? Explain.
(h) Here’s the observed data:x1= 3,x2= 10,x3= 5. Find an estimate forβusing method of moments.
(i) Here’s another observed data set:x1= 3,x2= 10,x3= 5000. Find an estimateforβusing method of moments.
(j) Now let’s think like a Bayesian. Consider a prior distribution ofβ∼Gamma(a,b)for somea,b >0. Derive the posterior distribution ofβgiven (X1,...,Xn) =(x1,...,xn).
(k) What is the posterior Bayes estimator ofβassuming squared error loss?

The librarian at the local elementary school claims that, on average, the books in the library are more than 20 years old. To test this claim, a student takes a sample of n=30 books and records the publication date for each. The sample produces an average age of M=23.8 years with a variance of s2 =67.5. Use this sample to conduct a one-tailed test with α=.01 to determine whether the average age of the library books in significantly greater than 20 years. Compute r2 and interpret..
Hypothesis Testing (Complete the four steps below)
STEP 1: State the hypotheses and set the alpha level (3 points)
STEP 2: Locate the critical region (3 points)
STEP 3: Compute the test statistic for the sample (6 points)
STEP 4: Make a decision and state your conclusion about H0 based on the result of step 3 (4 points) Compute and interpret r2. (4 points)
