QUESTION 1 a) The following values for the project: Activity time Early Start Early Finish Late Start Late Finish Slack Standard Deviation Project 36.33 1.56 A 10 0 10 0 10 0 0.67 B 9 0 9 9 18 9 2 C 8 0 8 2 10 2 0.33 D 2 9 11 18 20 9 0.33 E 10 10 20 10 20 0 0.67 F 6 20 26 20 26 0 0.33 G 3 20 23 23 26 3 0.67 H 5 26 31 26 31 0 1 I 4 23 27 32.33 36.33 9.33 0.67 J 5.33 31 36.33 31 36.33 0 0.67 K 2 31 33 34.33 36.33 3.33 0 We see from the output that the activities which have zero slack are activities A, E, F, H, J. Therefore, these activities are the critical path and thus the total duration is: 10 + 10 + 6 + 5 + 5.33 = 36.33 The project is expected to take 36.33 weeks b) We solve this using the following formula to get the …show more content…

2) Compute the standard deviation for each of the four samples. Does the assumption of .21 for the population standard deviation appear reasonable?
Guidelines are created to ensure a success interview process. Setup meeting time with the individuals, which will be interviewed and be prepared and on time. When conducting the interview examine the background of the organization and have a checklist readily available. Be on time for the interview be sure to pay close attention to what the user is saying and what the company are looking for. Refrain form using computer and information technology jargon. Collect both qualitative and quantitative information from the user. Distinguish between what is a desirable and essential requirement. Repeat back to the user what is
7. The data set for this problem can be found through the Pearson Materials in the Student Textbook Resource Access link,
• Include appropriate probability concepts and your application to find resulting data to limit uncertainty in this decision.
Using the statistical tables in your textbook, find the values of the appropriate test statistic in the following two situations:
If a die is rolled one time, find the probability of getting a number greater than 2.
2. At 95% confidence, use the p-value approach and test to determine if the average yearly income of marketing managers in the East is significantly different from the West.
Solutions Guide: Please do not present as your own. I sometimes post solutions that are totally mine, from the book’s solutions manual, or a mix of my work and the books solutions manual. But this is only meant as a solutions guide for you to answer the problem on your own. I recommend doing this with any content you buy online whether from me or from someone else.
The company should accept this project. The project payback period is between 2 to 3 years.
From the calculation (See Appendix I), we get the 3-sigma control limits for the process, i.e. UCL=0.091, LCL=0.014. These control limits indicate that if the error proportion is within the range of [0.014, 0.091], the process is under control; if not, the process is out of control.
There is a budget that used to explain the costs of a program you envision to your supervisor or Board. The emphasis here is training youth and helping them develop a deeper sense of community ownership and civic engagement, however when writing the initial budget, you can’t forget that the lead you assign to work on this project would have a large portion of their time occupied. This is not a volunteer-only program; it would rely on focused coordination and management from a member of your staff, and that must be factored into the overall cost.
In this case, level of significance, α was not provided. Therefore, the analysis will be evaluated based on two α values which are:

Project Description: Parque Eolico El Arrayan SpA (“El Arrayan” or the “Borrower”) is non-recourse, special-purpose entity formed to construct, own and operate a 115 MW wind farm located near Ovalla in the 4th region of Chile. El Arrayan is jointly-owned by Pattern Chile Holdings LLC, a subsidiary of Pattern Energy Group, LP (“Pattern”) (NR) (70%) and Antofagasta Minerals S.A. (“AMSA) (NR) (30%). The Project achieved COD on June 04, 2014 and has a 20-year energy supply agreement with Minera Los Pelambres, S.A. (“MLP” or the “Off-taker”), a subsidiary of AMSA, to sells up to 280,000 MWh annually through the Central Interconnection System (the “SIC”) and is supported by a financial energy hedge
-While service and production share many attributes, services have more diverse quality attributes than products. For example, product like a personal computer is typically evaluated on its merits, and it makes little difference to the user whether the person that assembled the computer was in a bad mood the day the computer was made. Service settings are more complex; thus quality is more difficult to define. A customer of a restaurant, for example, evaluates the quality of the restaurant not only on the merits of the food, but also on the demeanor of the employees, the speed of the
