6) A project has an expected completion time of 42 weeks and a standard deviation of 5 weeks. It is assumed that the project completion time is normally distributed (Total: 6 points). a) What is the probability of finishing the project in 52 weeks or less? (2 points) b) What is the probability of finishing the project in 40 weeks or less? (2 points) c) The due date for the project is set so that there is a 90% chance that the project will be finished by this date. What is the date? (2 points)

Step 1
The probability of finishing the project in 52 weeks or less: To find this, we need to calculate the z-score for 52 weeks. The z-score is calculated as (X - μ) / σ, where X is the value we're interested in, μ is the mean, and σ is the standard deviation. So, the Show more…

The completion time of a project is expected to be 44 weeks, with a standard deviation of 2.67 weeks. What is the probability that the project will NOT be finished in 52 weeks or less? 99.865% 100% 0.5 0.14% None of the above.

The time to complete a construction project is normally distributed with a mean of 60 weeks and a standard deviation of 4 weeks. (a) What is the probability the project will be finished in 62 weeks or less? (b) What is the probability the project will be finished in 66 weeks or less? (c) What is the probability the project will take longer than 65 weeks?

Your company is considering submitting a bid on a major project. You determine that the expected completion time for the project is 100 days, and that the standard deviation of the expected completion time is 8 days. (It is assumed that the normal distribution applies here.) You wish to set the project completion date in your bid such that there is an 80% chance that you will be able to complete the project by the date you have set. What due date should you set? What is the probability that the project described above is done within 90 days?
