Hey to all! I need to solve this task! It is the task for Bayesian networks subject. Someone can help?

We have two sensors that are meant to detect extreme temperature, which occurs 20% of the time. The sensors have identical specifications with a false positive rate of 1% and a false negative rate of 3%. If the power is off (dead battery), the sensors will read negative regardless of the temperature. Suppose now that we have two sensor kits: Kit A where both sensors receive power from the same battery, and Kit B where they receive power from independent batteries. Assuming that each battery has a 0.9 probability of power availability, compute the probability of extreme temperature given each of the following scenarios:

(a) The two sensors read negative.

(b) The two sensors read positive.

(c) One sensor reads positive while the other reads negative.

Thanks in advance!

Hey there,

would someone please be able to explain to me the realtionship between saturated soils and outflow rate? Is the rate of water flow faster when soil is not saturated as water is more easily able to travel through the soil? and in turn would saturated soils take longer for water to travel through? Please explain!

Hey there, Week 3 – Petrie’s Electronics Cases Ch 5/6 I need the answer for the hold project can you help me?Objectives Petrie’s Electronics needs to improve its marketing and customer retention by increasing customer loyalty. The marketing department is in need of a Customer Relationship Management (CRM) system. Upper management has selected No Customer Escapes as the top Information Technology project this year. 1. In Week 3, we move to the second phase of the system development life cycle (SDLC), System Analysis. This phase is where we gather information on the detailed requirements for the CRM project. 2. In order to gather detailed requirements, we will need to do the following.a. Continue reading in our book. Last week we read Chapter 3 and 4; this week we must understand all of the concepts in Chapters 5 and 6.b. Read the Petrie’s Case Questions at the end of Chapter 5 and 6 to add to what we learned in previous weeks.c. We have already gathered some requirements and constraints identified in PE Table 5-1 of our textbook.3. We will validate the requirements in Table 5-1 and gather additional requirements by using:a. Traditional method for Determining Requirements.•Interviewing stakeholders. •Observing workers. •Review existing documentation as described by Table 5-1 of our textbook. b. Modern Methods for Determining Requirements.•Joint Application and Design sessions. •Prototyping. c. Radical Methods for Determining Requirements.•Business Process Reengineering (BPR). •Disruptive Technologies. 4. To better understand a process for requirements gathering, we should review how Pine Valley Furniture will determine requirements for their Web store project in the book.5. The Petrie’s Electronics Case in Chapter 5 describes how you will collect requirements for the CRM project. The Project Manager has decided not to build the system in-house thanks to your Cost Benefit Analysis, but to research current customer loyalty systems in use in the market place today. Week 3 Project Tasks Back to Top 1.Read the Petrie’s Electronic Case at the end of Chapter 5. 2.Read the Petrie’s Electronic Case at the end of Chapter 6. 3.We have three deliverables due this week:Category Points1. Petrie’s Electronics Case, Chapter 5, Questions 1, 3, and 5. 15 2. Petrie’s Electronics Case, Chapter 6, Questions 1 and 5. 10 3. A Level 1 Data Flow Diagram decomposing the Record Customer Activity Process•Create a Level 1 Data Flow Diagram (DFD) using the Level 0 Diagram, PE Figure 6-2. There are four processes on the Level 0 another team has created level 1 diagrams for three processes and placed in doc sharing in the Project Workbook – Week 3 folder, Review them to ensure consistency: ◦Send Promotions Level 1 Diagram◦Generate Point Redemption Level 1 Diagram◦Generate Customer Reports Level 1 Diagram•We will need to create a level 1 diagram for the Record Activity Process using the Level 0 Diagram, PE Figure 6-2.•Please note the textbook has an error, PE Figure 6-2; The diagram is labeled as Level 1 DFD but it is actually the Level 0 diagram decomposed from the Context Diagram, PE Figure 6-1.•You can use MS Visio 2010 or any other MS Office Application (most students use Visio or WORD). 15 Systems Analysis SDLC Phase 2 Package part 140/40 Grading Rubrics Back to Top Answer the questions to the case studies below completely. Petrie’s Electronics Case Questions (Chapter 5) Points1. What do you think are the sources of the information Jim and his team collected? How do you think they collected all of that information? 5 3. If you were looking for alternative approaches for Petrie’s customer loyalty program, where would you look for information? Where would you start? How would you know when you were done? 5 5. Why shouldn’t Petrie’s staff build their own unique system in-house? 5 Total15 Petrie’s Electronics Case Questions (Chapter 6) Points1. Are the DFDs in PE Figures 6-1 and 6-2 balanced? Show that they are, or are not. If they are not balanced, how can they be fixed? • You need to understand the concept of “balance” between different levels of a DFD. Explain why/why not PE Figure 6-1 and PE Figure 6 -2 are balanced. The concept of balancing is described in the book.5. Why is it important for the team to create DFDs if they are not going to write the actual system code themselves? •You need to understand why DFDs are important and what they are used for! 5 Total10 The rubric below shows the required elements for the following deliverable: Level 1 Data Flow Diagram for the Record Customer Activities ProcessYou will need to create a level 1 diagram for the process Record Customer Activities from the level 0 diagram, PE Figure 6-2.You will need to turn in one level 1 diagram. Review the three level 1 diagrams created by the other team and placed in doc sharing in the Project Workbook – Week 3 folder.So you will need to draw one level 1 diagram. You can use any Microsoft Application; Visio is available for free download or you can use the Citrix iLab; but a lot of students use the draw features of MS Word. We have Visio tutorials available in the lecture and syllabus – give it a try! Visio is the most widely used diagramming tool in business today and you can gain practical experience that can serve both your resume and skill set!!Points1. Correct Number of Sub-Processes Identified. 5 2. Correct external entities identified. 3 3. Data Flows Drawn correctly. 4 4. Data Stores drawn correctly. 3 Total15

Hi- need your help in responding to a discussion post on the topic of correlation:

Some results that I can think of that applies not only to my department but my job as a whole is the amount of the raise given compared to the amount of money paid out for damages. I work in maintenance for a not for profit nursing home so we rely on grants. donations, and government funding. When something gets damaged by someone not taking care of equipment, it takes away from the money that would be going to raises and other improvements that could be made to the facility. As money goes out to pay for the damages, there is less money left over that could be used for higher raises or bonuses. It would be important as a manager to stress the importance of taking care of the equipment not only for the sake of bonuses and raises, but also to make sure that it lasts a long time.

Correlation coefficient tells me the direction and strength of association between twovariables. The significance of Correlation coefficient can be tested by t-test. I work inmaintenance for a…
