Below the triple point (-56.6°C) the vapor pressure of solid CO2 (also known as “dry ice”) is given as:

ln p = -3116/T + 16.01

The molar heat of melting of CO2 is 8330 J. Use just the data given here about CO2. State any assumptions you need to make to answer the following questions.

(a) Calculate the vapor pressure exerted by the liquid CO2 at 25°C.

(b) Explain why solid CO2 sitting on a laboratory bench evaporates rather than melts.

Identify a problem at a company that you feel can be improved by implementing a new process or technology. Note: This must be a real company and a real process that you feel needs improvement but the focus should NOT be on the company but rather on the process to be improved.

Note: You may want to start with either a problem that you have identified at a company OR a technology advancement or tool that you feel could help with a problem at a company, rather than starting with the company itself.

LO 1: STATEMENT OF PROBLEM

Identify an operations problem that could negatively affect the efficiency and/ or productivity of the organization. This problem must be one that can be resolved by implementing a new technology.

Clearly define the current process (“current state”), including the problem, in detail, and provide supporting flowcharts and diagrams. *You may have to create these.

Break up large problems into smaller sub-problems.

Clearly state the impact and the extent of the problem on the organization and/or customer

Clearly state the purpose of the paper as an attempt to solve the problem you have identified.

LO 2: PROBLEM ANALYSIS

Identify relevant factors leading to the problem (e.g. social, political, economic, and legal). One example of a factor would be an OSHA Safety Regulation.

Clearly state possible causes of the problem

Be sure to identify the difference between a symptom and a problem

Clearly state all issues (reasons why the problem is important to resolve), including any secondary or ‘non-obvious’ issues

Prioritize issues

LO 3: PROBLEM SOLUTIONS

Research emerging technology or process innovations that could be an opportunity for the company and this process.

Identify and describe a minimum of two possible solutions to the problem through the implementation of researched technology innovations.

Describe fully the possible solutions, including supporting flowcharts and diagrams

Discuss merits of both solutions, including all relevant factors necessary to make a decision between the two. Be sure not to neglect cost factors (you may need to provide estimated costs)

LO 4: SOLUTION JUSTIFICATION

Clearly state your proposed solution (one of the two options proposed in LO3: Problem Solutions)

Explain in detail why you are recommending this solution and how you feel it will specifically solve or alleviate the problem(s) and issues you identified (Justify solution)

Describe solution benefit(s)

Discuss the feasibility of the solution

Present an implementation plan for your proposed solution

OVERALL ASSESSMENT

Correctly defined terminology used

Used analytical tools and technology in paper

Performed appropriate calculations

Used analysis to find and justify decisions

Paper well organized and sections clearly defined

APA format

Correct grammar and spelling

Wells Fargo claims that the waiting time for its customers is the lower than at Bank of the West. You draw random samples of 30 customers at each bank. At Wells Fargo, the mean waiting time is found to be 5.3 minutes, with a standard deviation of 1.1 minutes. At Bank of the West, the mean waiting time is found to be 5.6 minutes with a standard deviation of 1.2 minutes. Test Wells Fargo’s claim at a 0.05 significance level. Let population 1 be Wells Fargo customers and population 2 be Bank of the West customers.

a) State the null and alternative hypotheses.

b) Find the value of the test statistic. You may use a graphing calculator. Round to three decimal places.

c) Find the P-value. You may use a graphing calculator. Round to three decimal places.

d) State whether you should reject or fail to reject the null hypothesis. Justify your answer.

e) State your conclusion in non-technical terms.

f) To construct a confidence interval for ?1 − ?2 that corresponds to this hypothesis test, what confidence level should you use? (90%, 95%, 99%, for example – a sketch may help)

g) Construct this confidence interval. You may use a graphing calculator. Round to three decimal places.

h) Explain why you reach the same conclusion with the confidence interval and the hypothesis test.

A social psychology professor is interested in determining whether education level is related to opinion on public funding for state universities. Complete the following. (1 point each)

1. Identify the data level(s) of the variables.
2. What statistical test would be appropriate to use? Explain the rationale for your answer.
3. Suggest how levels of these variables might be arranged in a table.
4. Write an example of how the null and alternative hypotheses for this test could be stated.
5. Assuming a statistically significant outcome, write a statement summarizing the conclusion.

a problem for inference in OLS regression

3. explain how it can be detected (if it can)   
4. state what action, if any, you should take to deal with the issue.
