What are some common logical fallacies (section 3.9) that you have witnessed in your life? (at work/school, in conversation, TV, Internet, etc.)
They can be related to technology, try not to get overly political in nature. Avoid Ad Hominem arguments in discussion.

Female primates visibly display their fertile window, often with red or pink coloration. Do humans also do this? A study looked at whether human females are more likely to wear red or pink during their fertile window (days 6-14 of their cycle). They collected data on 24 female undergraduates at the University of British Columbia, and asked each how many days it had been since her last period, and observed the color of her shirt. Of the 10 females in their fertile window, 4 were wearing red or pink shirts. Of the 14 females not in their fertile window, only 1 was wearing a red or pink shirt.
(a) State the null and alternative hypotheses. (2 points)
(b) Calculate the relevant sample statistic, ?̂? −?̂??, for the difference in proportion wearing a pink or red shirt between the fertile and not fertile groups. (2 points)
(c) For the 1000 statistics obtained from the simulated randomization samples, only 6 different values of the statistic, ?̂? − ?̂?? are possible. The table below shows the number of times each difference occurred among the 1000 randomizations. Calculate the p-value. (2 points) Randomization distribution for difference in proportion wearing red or pink in 1000 samples ?̂? −?̂?? −0.357 −0.186 −0.014 0.157 0.329 0.500 Count 39 223 401 264 68 5
(d) Interpret the p-value. (1 point)

1- Explain why it is necessary and important to analyze the marketing environment
2- For each actor/ force explained in the lecture (macro & micro) give a brief explanation, explain its important for marketers, find a real-life company example for each and explain in detail.
3- Choose a product, how would you market it to different generations? Explain your strategies for each generational cohort and indicate why you chose that strategy.

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.
