CompTIA Project+ (PK0-005) — Question 370

A project manager has determined that the critical path of a project is 243 days. However, knowing that the standard deviation is eight days, the project manager would like to provide an estimate to the stakeholders with 95% confidence. Which of the following time frames should the project manager communicate to the stakeholders?

Answer options

Correct answer: C

Explanation

The correct answer is C, as it corresponds to the critical path of 243 days, plus or minus 1.96 standard deviations (16 days total), resulting in a range of 227-259 days. The other options do not accurately reflect the 95% confidence interval calculated using the given standard deviation.
