Course Project - Phase 5, statistics homework help
This week you will submit Phase 5, the final phase, of your course project. For Phase 5 of your course project, you will want to review your instructor's feedback from your Phase 4 submission and make any necessary corrections. Remember if you have questions about the feedback to ask your instructor for assistance. Once you have made your corrections, you will make your final submission for the course project. Below is a summary of the expectations for Phase 5 of the course project: Introduce your scenario and data set. Provide a brief overview of the scenario you are given above and the data set that you will be analyzing. Classify the variables in your data set. Which variables are quantitative/qualitative? Which variables are discrete/continuous? Describe the level of measurement for each variable included in your data set. Discuss the importance of the Measures of Center and the Measures of Variation. What are the measures of center and why are they important? What are the measures of variation and why are they important? Calculate the measures of center and measures of variation. Interpret your results in context of the selected topic. Mean Median Mode Midrange Range Variance Standard Deviation Discuss the importance of constructing confidence intervals for the population mean. What are confidence intervals? What is a point estimate? What is the best point estimate for the population mean? Explain. Why do we need confidence intervals? Based on your selected topic, evaluate the following: Find the best point estimate of the population mean. Construct a 95% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown. Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations. Write a statement that correctly interprets the confidence interval in context of your selected topic. Based on your selected topic, evaluate the following: Find the best point estimate of the population mean. Construct a 99% confidence interval for the population mean. Assume that your data is normally distributed and σ is unknown. Please show your work for the construction of this confidence interval and be sure to use the Equation Editor to format your equations. Write a statement that correctly interprets the confidence interval in context of your selected topic. Compare and contrast your findings for the 95% and 99% confidence interval. Did you notice any changes in your interval estimate? Explain. What conclusion(s) can be drawn about your interval estimates when the confidence level is increased? Explain. Discuss the process for hypothesis testing. Discuss the 8 steps of hypothesis testing? When performing the 8 steps for hypothesis testing, which method do you prefer; P-Value method or Critical Value method? Why? Perform the hypothesis test. Option 1: Original Claim: The average salary for all jobs in Minnesota is less than $65,000. Test the claim using α = 0.05 and assume your data is normally distributed and σ is unknown. Based on your selected topic, answer the following: Write the null and alternative hypothesis symbolically and identify which hypothesis is the claim. Is the test two-tailed, left-tailed, or right-tailed? Explain. Which test statistic will you use for your hypothesis test; z-test or t-test? Explain. What is the value of the test-statistic? What is the P-value? What is the critical value? What is your decision; reject the null or do not reject the null? Explain why you made your decision including the results for your p-value and the critical value. State the final conclusion in non-technical terms. Conclusion Recap your ideas by summarizing the information presented in context of your chosen scenario. Please be sure to show all of your work and use the Equation Editor to format your equations.

Impacts of Employee Orientation on Job Satisfaction Research Paper
Final research paper, usually related to the previously submitted research proposal (but could be unrelated).
A typical paper structure would be the following -- but feel free to deviate from this if it doesn't seem to fit your research project well.
Abstract - executive (roughly 150 word) summary of the entire paper (2 marks)
I. Introduction - what is the research project about? (2 marks)
II. Motivation - why is this topic important? (2 marks)
III. Background - what background knowledge do we need to understand the research? (2 marks)
IV. Research Method - introducing research questions and methods for data collection and analysis
IV.A Research Questions - what is your research question / are your research questions? (3 marks)
IV.B Data Collection - what data did you collect (describe in enough detail that somebody else could reproduce)? (5 marks)
IV.C Data Analysis - how did you analyse this data (describe in enough detail that somebody else could reproduce)? (5 marks)
V. Findings - what did you find, i.e., what is the answer to your research question(s)? (3 marks)
VI. Discussion - how do you interpret the findings? This is where you can speculate a bit. (2 marks)
VII. Threats to Validity - what threats affect the validity of your findings? (7 marks)
VIII. Related Work - how does your research fit in with other researchers' work? (3 marks)
IX. Conclusions - a quick summary and concluding remarks (2 marks)
X. Future Work - what should others do next based on your work? (2 marks)

SMU Linear Block Cipher with Block Length N and Alphabet Cryptography Questions
Question 1: Consider the linear block cipher with block length n and alphabet
{0, 1}. On the key space of matrices A ∈ {0, 1}
(n,n)
with det(A) ≡ 1
(mod 2), choose the uniform distribution. Show that this cryptosystem
does not have perfect secrecy.
(Use the definition of perfect secrecy, and find a counterexample with n = 2, for instance.) 2: Let n be a positive integer. A Latin square of order n is an n × n
array L of the integers 1, 2, . . . , n such that every one of the n integers
occurs exactly once in each row and each column of L. An example of a
Latin square of order 3 is as follows:
1 2 3
3 1 2
2 3 1
.
Given any Latin square L of order n, we can define the following
cryptosystem: Take P = C = K = {1, 2, . . . , n}. For 1 ≤ i ≤ n, the
encryption function Ei
is defined to be Ei
(j) = L(i, j). (Hence each row
of L gives rise to one encryption function.)
Give a complete proof that this Latin square cryptosystem achieves
perfect secrecy. (Use Shannon’s theorem).If the question descriptions not clear enough, please check the picture file I posted.
