A project has the following activities, with specified precedents and expected durations (in days). What is the expected project duration?

Select a project in Ghana, say Ghana’s National Health Insurance or planting for food and jobs, and specify the following along the Result Chain. 1. The project output(s), outcome(s), and the impact (Goal)2. Provide the indicator(s) for measuring the output(s), outcome(s), and impact, and define the various indicators used. 3. List/show the baseline, target, means of verification, frequency and responsibility under the resulting chain ie input(s), output(s), outcome(s), and impact.Below is the operational definition for some key terms in the assignment. Impact (Goal): The ultimate goal or change that the project or program aims to achieve.Outcomes: The specific changes or benefits that are expected to result from the project’s activities.Outputs: The tangible products, services, or goods that result from project activities.• Indicator: These are measurable signs of change or progress which are used to assess whether the project is achieving its outcomes and outputs. • Indicator…

The following table shows estimates of activity times (in weeks) for a project: Optimistic Time 5 Activity A B с D EFG 1 4 5 6 2.5 7.5 Most Probable Time 5.5 3 5 5.5 7 b. What is the probability that the project will be completed within 31 weeks? 3 8.5 Suppose that the critical path is A-C-D-E-G. Use Appendix A to answer the questions. Do not round intermediate calculations. Round your answers to three decimal places. a. What is the probability that the project will be completed within 34 weeks? d. What is the probability that the project will be completed in 33 weeks? C. What is the probability that the project will be completed in more than 32 weeks? Pessimistic Time 9 5 6 9 8 3.5 12.5

Using the following table, calculate the project duration   Task Predecessor Duration (weeks) A - 1 B A 2 C - 2 D - 3 E B 3 F C, D 4 G E,F 6 H F 1
