A homeowner recorded the amount of electricity in kilowatt-hours (KWH) consumed in his house on each of 21 days. He also recorded the numbers of hours his air conditioner (AC) was turned on and the numbers of times his electric clothes dryer (DRYER) was operated. His objective was to relate the KWH consumption to the AC and DRYER usage. In addition, he wanted to know how many KWH’s the AC used per hour and the number of KWH’s used in each run of the DRYER. Statistical regression analysis can serve this purpose. Use chapter 14 as a guideline to develop a regression model that predicts KWH consumption from AC and Dryer usage. 1. Perform a simple linear regression using only AC to predict KWH. 2. Perform a simple linear regression using only Dryer to predict KWH. 3. Perform a multiple linear regression using both AC and Dryer to predict KWH. 4. Compare pvalues for the F-test, Rsquare, and the regression coeficients for the results of 1, 2, and 3. To maximize participation (and credit), do task 1 and 2 on one day, 3 on the second day, and 4 on the third day for a total of three posts. Question 1

...KMGT-680-2A: Introduction to Project Management
Discussion Question (7)
H000319111
When a project comes to an end successfully, it shows that it was handled well which creates an avenue for more projects in the future. The experiences gotten by the team members will increase and they will work well because they have been appraised from the just concluded one. The reputation of the company is also rated high because the PM and the team have performed but the reverse will be the case if clients have complains from completed projects.
The PMLC is an aspect that should be carried out properly because it tells how well the preparation was done eg, planning, scoping lunching and control and monitoring. The ceremonial and formal processes are ways in which a PM can know if his/her client is happy with the outcome of the project and it simply shows the actions taken towards every task to meet the stakeholder’s requirement (Wysocki, pg.313). Before a project starts, there must be an agreement between the PM and the stakeholder. If the PM carries out all that was agreed to do during the scoping and planning phase, and he meets up with the time and budget, the stakeholder will be excited.
At the completion of every project, it is always good to hand over to the client in good condition and he should be put through on how things are operated ie, testing of equipment and presentation. This will go a long way in the rating of the firm and the PM. For...

Comparing First-movers in Technology"
From the first and second e-Activities, analyze the key ways in which Intel and Microsoft capitalized on and reaped substantial first-mover advantages in pioneering new technologies. Provide a rationale to support your response.
Answer：Both companies have made major impacts on the world for two different reasons. Microsoft is thoroughly known for the famous operating systems whereas Intel made the first microprocessor. What made them unique is they didn’t really sell the same items. They differentiated their products and let technology mold and develop them for the people’s needs. Intel and Microsoft are able to sell to the same consumers because the demand is for two different products. Intel essentially made this all possible by creating the processor. Microsoft is fast moving to make them keep up with the times with making their products work with any known threats like the Cloud as well as integrating itself into smart phones and gaming applications. Instead of making new products they incorporate the competitions threat into their products thus making a sense of synergy. Microsoft also continues to capitalize by fixing problems, hearing consumers, and making operating platforms more consumer efficient.
From the first and second e-Activities, compare Intel’s and Microsoft’s strategies in terms of their ability to profit from innovation. Next, analyze the manner in which shifts in new...

...There are many ways that a company can motivate its employees. Consider the different types of pay and benefits described on pp. 420–423 of the text. What type of incentive do you think is most effective for creating a motivating work environment? Why?
Creating a motivating work environment can be a difficult task. Employers need to consider the needs of employees and the average pay rates for the work required when determining salaries and benefits. To keep employees motivated, it is important to offer incentives and pay raises for good performance. When employers base their raises on the merit pay system, they will encourage their employees to work hard to earn a high raise. Also, providing employees with bonuses when they accomplish a designated task will keep them encouraged to work hard. One thing that employers should consider when determining the salaries and benefits of employees is health insurance. Many people cannot afford for health insurance to come out of their base pay. Therefore, if employers pay for the health insurance for full time employees, they will be more likely to keep employees. Although paid time off and sick days are luxuries that employees appreciate, health insurance is the most important benefit that an employer can offer.

1. Find the Week 4 Resources for WLDN 1000 and open the document titled What is a Rubric (and Why Should I Use One?). Copy and paste the first paragraph of the Word document here.
A rubric is a document that states the criteria, or guidelines, for grading an assignment. Instructors use rubrics to ensure that an assignment meets stated criteria. Another purpose of a rubric is to promote fairness in evaluation—that is, ensuring that all students are evaluated by the same terms.
2. Describe one feature of your Technology Contingency Plan. (Hint: This is in Module 2 of the SRO.)
File Backup Schedule
It is important to backup your files regularly. A best practice is to select a time and day each week to complete this task, then write it on your weekly calendar.

Meliah,
Good post and I choose game theory as well. Game theory deals with any situation in which the reward of any one player (called the payoff) depends on not only his or her own actions but also on those of other players in the game. Game theory provides a technique that is suited to investigate such interactions, but as applied in the research literature it is a far more mathematical treatment than might be suggested by our attempt to explain its nature in a simple way.

Suppose you provide consulting services on price-setting strategies to a number of airline companies. Please respond to the following questions based on the lecture concepts of this week.
In what way the “game theory” can be a useful optimization tool in making pricing decisions by airlines?
Baggage fees introduced by airlines provides for an interesting game theoretic analysis between the various stakeholders. Based on ones goals, each air lines choose certain actions and decides whether to go along with a competitor and play the game or to stay out and follow a different strategy.
While majority of the airlines are benefiting from baggage fees, the success of that initiative is critically dependent on co-operation among the major airlines. If one airline pulls out, the whole program will fall like a house of cards. So far co-operation has been sustained and everyone...

Quiz Review for Weeks 5 and 6
1. Find the area under the standard normal curve between z = 1.6 and z = 2.6.
First we look for the area of both by doing “2nd ,Vars, NORMALCDF” and inputting “-1000, “Z,” 0, 1 then find the difference between both.
2. A business wants to estimate the true mean annual income of its customers. It randomly samples 220 of its customers. The mean annual income was $61,400 with a standard deviation of $2,200. Find a 95% confidence interval for the true mean annual income of the business’ customers.
First we find E by doing Zc(standard deviation/square root of number of trials.) Now we add and subtract that number from the mean income to find both endpoints. The Zc of 95% is 1.96 so we would do 1.96((2200)/square root of 220) giving us 290.71. Now if we subtract that from the mean income, we get 61109.29 as the left endpoint and 61690.71 as the right endpoint.
3. IQ test scores are normally distributed with a mean of 100 and a standard deviation of 15. An individual's IQ score is found to be 120. Find the z-score corresponding to this value. “X-mean/standard deviation. (120-100)/15
4. Two high school students took equivalent language tests, one in German and one in French. The student taking the German test, for which the mean was 66 and the standard deviation was 8, scored an 82, while the student taking the French test, for which the mean was 27 and the standard deviation was 5, scored a 35. Compare the scores. Same...
