Quantitative methods and analysis

You have learned about three different types of distributions: Normal, binomial, and Poisson. You can take data that you collect and plot it out onto graphs to see a visual representation of the data. By simply looking at data on a graph, you can tell a lot about how related your observed data are and if they fit into a normal distribution.

For this submission, you will be given a series of scenarios and small collections of data. You should plot the data or calculate probabilities using excel. Then, you will create your own real or hypothetical scenario to graph and explain.

Answer the following:

The mean temperature for the month of July in Boston, Massachusetts is 73 degrees Fahrenheit. Plot the following data, which represent the observed mean temperature in Boston over the last 20 years:
1998 72 1999 69 2000 78 2001 70 2002 67 2003 74 2004 73 2005 65 2006 77 2007 71 2008 75 2009 68 2010 72 2011 77 2012 65 2013 79 2014 77 2015 78 2016 72 2017 74

Is this a normal distribution? Explain your reasoning.
What is an outlier? Are there any outliers in this distribution? Explain your reasoning fully.
Using the above data, what is the probability that the mean will be over 76 in any given July?
Using the above data, what is the probability that the mean will be over 80 in any given July?
A heatwave is defined as 3 or more days in a row with a high temperature over 90 degrees Fahrenheit. Given the following high temperatures recorded over a period of 20 days, what is the probability that there will be a heatwave in the next 10 days?

Day 1 93 Day 2 88 Day 3 91 Day 4 86 Day 5 92 Day 6 91 Day 7 90 Day 8 88 Day 9 85 Day 10 91 Day 11 84 Day 12 86 Day 13 85 Day 14 90 Day 15 92 Day 16 89 Day 17 88 Day 18 90 Day 19 88 Day 20 90
Customer surveys reveal that 40% of customers purchase products online versus in the physical store location. Suppose that this business makes 12 sales in a given day

Does this situation fit the parameters for a binomial distribution? Explain why or why not?
Find the probability of the 12 sales on a given day exactly 4 are made online
Find the probability of the 12 sales fewer than 6 are made online
Find the probability of the 12 sales more than 8 are made online

Your own example:

Choose a company that you have recently seen in the news because it is having some sort of problem or scandal, and complete the following:
Discuss the situation, and describe how the company could use distributions and probability statistics to learn more about how the scandal could affect its business.
If you were a business analyst for the company, what research would you want to do, and what kind of data would you want to collect to create a distribution?
Would this be a standard, binomial, or Poisson distribution? Why?
List and discuss at least 3 questions that you would want to create probabilities for (e.g., What is the chance that the company loses 10% of its customers in the next year?)
What would you hope to learn from calculating these probabilities?
Assuming that upper management does not see the value in expending the time and money necessary to collect data to analyze, make an argument (at least 100 words) convincing them that the expenditure is necessary and explaining some dangers the company could face by not knowing what the data predict.

Breach Of Contract

Read the scenario and respond according to the prompts below.
Mary tells Liam and Mike that she will give them $2,500 if they paint her house. Mary’s statements are overheard by Jane, Mary’s neighbor. The next day while Mary is at work, she sees an ad by Bill’s painting that states “Bill’s will paint your house for $1,500, satisfaction guaranteed or your money back.” Mary calls’ Bill’s and arranges to have her house painted. When Mary returns home, she finds Liam and Mike hard at work and her house half painted. She screams at them to stop and orders them off her property. Bill’s workers come the next day and paint the house. Liam and Mike come to you for advice because Mary refuses to pay them.
Write a formal paper that discusses issues that you identify in the scenario. (note: unlike prior assignments, in this Week 3 paper, you must identify the issues. Remember, this assignment is 26% of your course grade)
Some items to consider:
What claims might Liam and Mike have against Mary?
What defenses might Mary have?
If Liam and Mike have valid claims, what damages might they recover?

Decision-making with Technology Analysis paper

Overview:
In all business areas making decisions is a natural and integral part of any company’s management process. Technology is taking on an increasingly major role in decision-making today. The sheer amount of data that managers must operate with on a daily basis is absolutely staggering compared to what they had to work with just a few decades ago. In todays world, BI-centered
tools are a critical component of any successful company’s strategy. They allow managers to streamline the effort needed to search for, combine
and query data to obtain the information required for good decisions.
Describe two key system-oriented / technology trends that have brought IS-supported decision making to the forefront of the decision analysis field in recent years.
List and describe two capabilities of computing that can facilitate good managerial decision-making.
How can information systems and tools help overcome the cognitive limits of humans?
Guidelines for Submission: Using APA 6th edition style standards, submit a Word document that is 2-3
pages in length (excluding title page,
references, and appendices) and include at least two credible scholarly references to support your findings.
Be sure to cite and reference your work using the APA guides and essay template that are located in the course room.

Software Development Processes Discussion Paper

Your team has been tasked to develop a small application that examines all the pictures in a users photo library. The application identifies pictures that are of the same subject and suggests the best among those similar pictures. The user then may ask the application to delete all the similar photos except the one the application suggests is the best. Alternatively, the user may delete user-selected photos from the set of similar photos, leaving the rest in the photo library.
Your team has identified the following subsystems as part of the application architecture:
1. User Interface
2. Find Similar Pictures
3. Identify the best among similar pictures
4. Delete as requested
If you were to do intermediate design on the fourth subsystem using one of the Divide and Conquer approaches, which would you use and why?

Unified Communication Platforms

Unified Communication Platforms
Based on your Week Two Learning Team Collaborative discussion, submit, individually, a 2 page APA formatted paper with a comparison of the different kinds of unified communication platforms, such as VoIP and PBX, their features and functionality, with example applications such as Skype or others similar, based on the five criteria.

a.Per the textbook, in order to understand the causal relationship in business process, manager often asks
whys to drill down the root cause of failures. Select one (1) project from your working or educational
environment and propose at least three (3) why questions that you would ask in order to identify root cause
of problem. Justify your responses.
b.The data in the table below is from a study conducted by an insurance company to determine the effect
of changing the process by which insurance claims are approved. The goal was to improve policyholder
satisfaction by speeding up the process and eliminating some non-value-added approval steps in the
process. The response measured was the average time required to approve and mail all claims initiated in
a week. The new procedure was tested for 12 weeks, and the results were compared to the process
performance for the 12 weeks prior to instituting the change.
Table: Insurance Claim Approval Times (days)
Old Process New Process
Week Elapsed Time Week Elapsed Time
1 31.7 13 24
2 27 14 25.8
3 33.8 15 31
4 30 16 23.5
5 32.5 17 28.5
6 33.5 18 25.6
7 38.2 19 28.7
8 37.5 20 27.4
9 29 21 28.5
10 31.3 22 25.2
11 38.6 23 24.5
12 39.3 24 23.5
Use the date in table above and answer the following questions in the space provided below:
1.What was the average effect of the process change? Did the process average increase or decrease and
by how much?
2.Analyze the data using the regression modely=b0 +b1x, wherey= time to approve and mail a claim
(weekly average),x= 0 for the old process, andx= 1 for the new process.
3.How does this model measure the effect of the process change?
4.How much did the process performance change on the average? (Hint: Compare the values ofb1 and the
average of new process performance minus the average of the performance of the old process.)
