[SOLVED] Mathematical Concept
Math 105 Final Project TopicsASSIGNMENT Write a 3-5 page paper answering one of the following questions.DUE Sunday 15 December @ 10:00am Hard copy in my office.Topic One: You are a Mathematics Instructor tasked with creating a case study for your students.Write a case parallel in idea to the case titled Consumers Sometimes Need to do the Math. The case explained a mathematical concept and compared it topsychology the concept of delayed gratification. Your task is to design a case in the same way for students. At the end of the case, create 6-8questions and answer them. Implement a project topic at the end of the case and create an outline to address the topic.Reflection: Do you find case studies that pair a mathematical concept to a real life application help portray the idea in a clearer way to students? For example, the case comparedthe decision to purchasing a specific product to the psychological idea of delayed gratification and then used the example of the fridge asan application. Why or why not?Topic Two: You are a writer for a journal, and you are tasked with a highlight on different cryptography methods used in history and our modern day world.Write about cryptography and how it has been used historically and in our modern day world. Explainwhat it is, how it is used and highlight 8-10 different methods and their uses.Research and investigate 8-10 occurrences/events where cryptography was used. This could come from a historical or fictional event/time. Familiarize yourself with what happened and be prepared to shareit within the journal.For every example explain the event/method where cryptography was used. When and where did it occur? How did itoccur? Why? Who was involved? What was the impact of the coded message? What kind of coding method was used?Reflection: Do you think cryptography is still used today? Is it still necessary or valid? Why or why not? Do you think you or your peers will ever need to use cryptographyWhy/how? Why not?Topic Three: You are a mathematics instructor tasked with creating a short guide on conversions for your students.Write about conversions what are they used for, and how?

A psychologist hypothesized that biological males are more likely than biological females to accumulate objects of trivial significance because of a biological basis to acquire and possess. Both male and female students were loaned No. 2 pencils with which to take a multiple?choice exam. A box labeled pencils was positioned next to a table upon which students were to place their answer sheets. The investigator counted the number of males and females who returned the pencils. The hypothesis was that males would be more likely to keep the object. Conduct a chi?square test to analyze the data. If there is evidence of an effect, what is the effect size?

In fantasy baseball, groups of pretend owners conduct a draft in which they can buy baseball players to fill out their roster for an upcoming season. These made?up teams are then compared based on the individual performance of each team member of each team. At the end of the season, team winners are declared based on the cumulative performance of the roster of players. This practice has become quite popular and many leagues of friends have stayed together for 20 years or more. Because of some small rule differences between the two leagues within professional baseball, players drafted from National League teams tend to have better defensive numbers, while players drafted from American League teams tend to have better offensive numbers. This opens the door to an interesting question: Is there an advantage to drafting players from one league or the other (all other things being equal) in a fantasy league situation? One way to look at this issue might be to see which made?up teams have won the fantasy league in the past teams with predominantly National League players or teams with predominantly American League players. If we had access to this data, describe a methodological situation that would employ the following analytical tools.A. A chi?square goodness?of?fit testB. A point?biserial correlationC. A Spearman rank correlation.
[SOLVED] Hypothesis Testing the Golden Ratio
The Golden Ratio, sometimes referred to as Phi (, is a ratio between two lengths A and B that yield the exact number which is irrational and is approximately We will use 1.62 as our approximation for the purposes of this hypothesis test. Many claims have been made that the golden ratio exists in nature both in living and non-living things.For example, the length of a human arm from elbow to wrist compared to the length of the hand from wrist to tip of middle finger. In this example, the length from elbow to wrist would be length A and the length from wrist to middle finger would be length B.To test a claim such as this, suppose we collected a large data set and fond the mean average ratio for all the ratios collected to be 1.71. This is indeed close to 1.62, but do we then agree with the claim that human arms and hands grow in an approximate golden ratio? What if the original claim was that this human ratio was which is approximately ? Do our findings support this claim? This example shows why we never, ever support the null hypothesis with our findings. We may only reject it due to strong evidence to the contrary, or fail to reject it due to insufficient evidence to the contrary.

[SOLVED] Global Marketing Environment
Global Marketing EnvironmentThis competency assessment assesses the following Outcome: COUNTRY OF CHOICE IS FRANCEMT219M2-2: Examine global interconnectedness as it applies to marketing.Organizations interested in pursuing global markets must consider the external environment. Many of the same environmental forces that relate to domestic markets also apply to global markets (Lamb et al., 2021). You will look at the global marketplace in which, thanks to the Internet, even small companies can participate. The external marketing environment is full of opportunities and threats that can have a profound effect on the success or failure of a company, a brand, or a product in the global marketplace.In this assessment, you will practice scanning the global marketing environment (i.e., environmental analysis) for opportunities or threats to expansion in a country of your choice outside the U.S. for Persimmon Bakery as the owner.Scenario: You are the owner of Persimmon Bakery, which is currently located in the city closest to where you live. (JACKSONVILLE FL.) You specialize in breads and sweets from many different countries and now have operations in eight regions of the U.S. You realize the market has become saturated in the U.S. At a recent international trade show, you were surprised at how many requests you received to license or franchise your concept in other countries.Your task is the following:Based on the scenario, identify another country outside the United States to research and determine the feasibility of entering this foreign market for Persimmon Bakery as the owner by addressing the checklist items in a minimum 10-slide Microsoft® PowerPoint® presentationChecklist:Step 1: Cultural Factors Identify several cultural factors in the country you are pursuing that may affect market expansion of the bakery, such as: behavior patterns, the concept of time, lifestyle, etc. You can useCommisceo Global Consultants website to research country cultural factors.

Explain why these demographic factors are opportunities or threats to entering this market.Step 3: Economic FactorsAccess The World Factbook from the CIA and select the country of choice in the upper right hand corner search box. Identify these three economic factors in the country you are pursuing: GDP per capita (see the Learn: reading resources area), GDP growth rate, and theunemployment rate in your chosen country. Explain why these economic factors are opportunities or threats to entering this market based on the country you chose.Use bulleted points to make your main points (34 bullets per slide) and then explain those bulleted points in the notes section directly under the slide.Step 4: Political/Legal Forces-Go to the World Bank Groups Doing Business website and note the Ease of Doing Business ranking-Then go the World Economic Forums website for country and regional trends from the NRI.Provide the four rankings for your chosen country.
