Explanation & Answer
x+2=4
and x+2=6.
these called inconsistent equation because for the same value of x, one equation dont satisfy the value.add me as your tutor for help.love to explain you.

provide examples.DQ 2When building a model, how do you know if it is the correct one? Are
you able to trust the model that you built in order to apply the data
correctly to solve a company's problem?AssignmentYou will need to build a model that will solve the problem that you
have identified. Use one or more of the following software
applications: IBM SPSS Modeler, SPSS Statistics, Excel, Tableau, or R.Write a 500-750 word paper describing your model. It will include
the following: What models did you build? Why did you choose this
model(s)? Be sure that this model specifically ties back to the
business problem you created for the Topic 1 assignment.
What variables did you include or leave out and why?
Provide specific screenshots from the modeling software in your
paper. Provide the raw software files that you used for this assignment

STAT 2002 Walden University Week 6 Statistical Process Control to Manage Processes PPT
Backround: For this Assignment, you will be tasked with creating a presentation for a group of business leaders to explain statistical process control (SPC) and to identify some examples of the use of SPC to promote sound business decisions.You work as a business analyst within the IT Department of XYZ Corporation and have just been put on assignment as a consultant to a health care organization. In this organization, there is a clinical “Nurse Helpline” call center, which has a staff of several experienced nurses and nurse practitioners to answer telephone calls from outpatients who have concerns about their health or the treatment or medications they are receiving from the hospital. One of the leading metrics in this call center is hold times. They have a standard that any call placed on hold is not in hold status for more than 2 minutes before an interaction with a nurse. Every day, each clinic records the number of calls and the number of calls on hold answered in less than 2 minutes. The management team has concerns about the number of calls that have hold times greater than 2 minutes. They want to employ a more formal quality control process that would allow them to get ahead of the problem, which is why you have been consulted.During your initial interactions with the hospital and management team, you talk informally about the use of statistical process control (SPC). You soon realize, however, that some members of the management team may not have a true understanding of how SPC would work in their organization. One member in particular asks a surprising question that makes you wonder if part of the management team is missing even a basic understanding of SPC. So, you decide to create a presentation that explains what statistical process control is and provide the management team with some examples of how SPC can be used in a business context to promote sound decision making. To support the information that you provide in your presentation, be sure to reference a minimum of four properly formatted, scholarly sources.Power point presentation with speaker notes- Please use the power point template, because I will need to submit it !Part 1: Explaining Statistical Process Control (8–10 slides, with speaker’s notes)Define statistical process control (SPC) and briefly describe the history of SPC, focusing on its origins. (2 slides)Provide an example of a control chart (either one you create or one you locate on the web) and label the parts of the chart. (1 slide)Describe the derivation of the center line and control limits on a control chart and the meaning of each. (1–2 slides)Explain the two types of process variation—common cause and special cause. (2 slides)Describe at least two signals of special cause variation that might be detected in a control chart. (2–3 slides)Part 2: Applications of SPC in Business Decision Making (5–8 slides, with speaker’s notes)Identify at least two examples of the application of SPC in a business context. Select examples from multiple industries (e.g., manufacturing, health care, and service). For each example, describe how SPC was used to improve process, achieve better outcomes, and support sound decision making. (2–4 slides)For each type of process variation, describe the implications for management action. (2 slides) In conclusion, provide three potential benefits of SPC to the health care organization. Specifically, how might SPC help the company make sound decisions to the end of achieving its goals? Also, what, if any, drawbacks do you see to using SPC? Identify two possible risks of the use of SPC that the organization should be aware of. (1–2 slides)Note: Your presentation should adhere to the template provided. It should consist of 13–18 slides, not including the title slide and References slide that includes properly formatted citations for a minimum of four scholarly sources to support the information you presented. You should also include detailed speaker notes, to be used as a script for delivering the presentationTRY TO FOLLOW THE POWER POINT TEMPLATE!

Probability and Probability Distributions
Part 1: You are the healthcare administration leader for a health services organization and are interested in achieving a standard, whereby 90% of all patients are screened within the initial 15 minutes of arriving for a family practice appointment. In a random sample of 30 patients, you find that 25 were screened within 15 minutes. The probability that this event (or one more extreme) would occur, might be modeled as a binomial with the following probability statement: P(X≤25 | N=30, p=0.9) To solve, you use =binom.dist(25, 30, 0.9, TRUE) in Excel and find that you would expect 25 or fewer screenings in 30 trials when the success rate should be 0.9 about 17.5% of the time. Review the resources and consider how one of the distributions presented might be useful for healthcare administration leaders. Describe in 2 or 3 paragraphs an example of how one of the distributions presented might be used in your health services organization or one with which you are familiar. Then, generate a representative probability statement based on the scenario and solve using fictitious data. Be specific in your probability statement. Part 2: Your company is running a Medicare audit on Sleaze Hospital. Because Sleaze has a history of overbilling, the focus of your audit is on checking whether the billing amounts are correct. Assume that each invoice is for too high an amount with probability 0.06 and for too low an amount with probability 0.01 (so that the probability of a correct billing is 0.93). Also, assume that the outcome for any invoice is probabilistically independent of the outcomes for other invoices. For this Assignment, reflect on the case presented. Think about what strategies you might use to calculate associated probabilities for Sleaze Hospital, and then address the series of questions. The Assignment: (3–5 pages) If you randomly sample 200 of Sleaze's invoices, what is the probability that you will find at least 15 invoices that overcharge the customer? What is the probability you won't find any that undercharge the customer?Find an integer, k, such that the probability is at least 0.99 that you will find at least k invoices that overcharge the customer. (Hint: Use trial and error with the BINOMDIST function to find k.)Suppose that when Sleaze overcharges Medicare, the distribution of the amount overcharged (expressed as a percentage of the correct billing amount) is normally distributed with mean 15% and standard deviation 4%.What percentage of overbilled invoices are at least 10% more than the legal billing amount?What percentage of all invoices are at least 10% more than the legal billing amount?If your auditing company samples 200 randomly chosen invoices, what is the probability that it will find at least five where Medicare was overcharged by at least 10%?References:Albright, S.
