Imagine you are working in the marketing department of a company. Your supervisor assumes that if the
company spends more on digital advertisements it would lead to an increase in sales. In fact, she hopes
that doubling the budget for digital advertising will result in daily sales that are greater than $10,000. She
wants to solve the problem at hand and asks you to investigate. To verify this assumption, the marketing
department will raise the digital advertisement budget for a six-month period, then analyze the collected
data at the end of that period.
You collect monthly data from the past six months and then randomly sample 30 days. The results of your
sample and your calculations are shown in the Excel file provided in the assignment instructions.
Write a two to three (2–3) page report using the provided template in which you:
1. Construct a box-and-whisker plot for the daily sales.
2. Copy the sample mean, median, and standard deviation for the daily sales.
3. Copy the 95% Confidence Interval for the daily sales.
4. Conduct a hypothesis test to verify if the claim that the mean daily sales is greater than $10,000
is supported. Clearly state the logic of your test, the calculations, and the conclusion of your test.
5. Provide the following discussion based on the conclusion of your test:
a. If you conclude that the mean daily sales is greater than $10,000, provide three (3)
possible causes. Share marketing strategies that will support this upward trend the
company is experiencing.
Or
b. If you conclude that the claim of mean daily sales is not greater than $10,000 is not
supported or justified, provide a detailed explanation to your supervisor of how the
company can increase daily sales. Include marketing strategies that will support an
increase in daily sales. Include your speculation on the reason(s) behind the claim.

Instead of lecture questions you will again be making a concept map covering sections 5.1-5.3 below. Remember to include prepositions and a paragraph explaining your thought process in creating your map. Dont forget prepositions.

Part 1
The purpose of this activity is to find a model for linear data and to make predictions. 
Everyone will be working with the same two pieces of data but you will be asking different people and therefore will have slightly different results. Your goal is to find the relationship between height (in inches) and shoe size.
1. Ask 10 different people how tall they are (in inches) and their shoe size. Record your responses in a table here. (+5)
2. Put your paired data into statcrunch and run the linear regression. What is the equation of your line of best fit? (+2)
3. Using your equation from statcrunch, predict the shoe size of someone who is 60 inches tall. (+2)

Part 2
Answer the questions in the document attached watching these videos

Refer to these videos to answer questions on worksheet attached

———-
The purpose of this activity is two fold. Can you create a graph from data you collect and can you explain what is misleading about a graph.
Part 1:
1. Create a question that you can ask 10 people. Write the question you created and the results. (+2)
2. Create a graph of your choosing which represents the results. Briefly explain why you chose this type of graph. (+2)
Part 2: 
3. Do a google search for a misleading graph. Add either the image or the weblink for this graph (+2)
4. Briefly explain what is misleading about this graph and what you would do to fix it (+2)
5. After you have completed your post, find a classmates post and comment on their graph construction. Do you agree with their choice of graph? Is there anything they could do to improve their graph? (+2)

  Unit 4, we are learning about the graph theory. For this discussion, you will post at least twice – 1) an initial post, and then 2) a reply to a classmate.
For your initial posting, based on the concepts from this unit, answer at least one of the following:
Share a thing that you learned about graph theory.
Share a resource you found that was helpful to your understanding of the concepts in this unit.
Ask a question about graph theory.
Post a relevant or encouraging meme about graph theory.

 
You are the vehicle dispatcher for a delivery service that serves a mix of ‘easy’ customers who are quite pleasant when the driver arrives and ‘hard’ customers who are difficult to manage. In order to keep the drivers happy, you never assign a driver to visit two hard customers in a row. Thus, for each driver, given a set of ‘easy’ and ‘hard’ customers to visit, your goal is to minimize the travel time to visit all customers, starting and returning from the company depot, satisfying the constraint that a hard customer visit cannot be followed by another hard customer.
This problem can be infeasible if the number of hard customers is greater than the number of easy customers. Let’s assume that this is sometimes the case. As dispatcher, you have decided to relax the constraint that a hard customer visit cannot be followed by another hard customer. Rather, you want to minimize the number of times this happens and minimize the route travel length.
It may not be possible to minimize both terms at once; how would you find a good compromise?
Formulate the Hard/Easy Customer Traveling Salesman Problem (TSP) with the two term objective function terms. Define any new notation you introduce and explain your formulation in words and present mathematically.
Develop a heuristic to solve the problem. Clearly present your heuristic.
Solve the instances posted in the excel file. Solutions should include the visit sequence of nodes and the tour length and # of times a hard customer follows another hard customer for each instance. Your solution should be included on the tab “Sample solution” in the data spreadsheet.
