the standard normal table. (Make sure to round all intermediate calculations for t, and variance to two decimal places)
The probability that the seminar will be ready in time is 0.8643]. (Enter your response rounded to four decimal places.)
We are the project manager for an IT project in our company. We identified the following top-level project tasks and estimated durations to standup a small test lab for the project:
Identify test lab building/space requirements and possible locations(8days)
Select best location for lab (1day)
Once the best location is selected, immediately start the next two tasks:
Prepare lab space with power and cabling (3days)
Identify/procure required specialized test lab hardware/software(5)
Once the lab space is prepared, install/check out available infrastructure hardware/software(1day).
Once the specialized software/hardware is received and the infrastructure hardware/software is installed/checked out, install/checkout specialized software/hardware (2days)
Once all tasks are completed, conduct the final inspection (1 day).
Let's create a PERT/CPM chart for this project and identify the overall project duration and critical path.
The table below contains data for the installation of new equipment in a manufacturing process at Excello Corporation. Your company is responsible for the installation project. Indirect costs are $12,000 per
week, and a penalty cost of $6,000 per week will be incurred by your company for every week the project is delayed beyond week 12.
