You have just used the network planning model for a county road resurfacing project and found the critical path length is 40 days and the standard deviation of the critical path is 10 days. Suppose you want to pick a time (in days) within which you will complete the project with 90% confidence level. What should be that time (in days and round to the nearest whole number)

The answer is "53 days"

Step-by-step explanation:

The form for the due date is given below from the above information.

The level of confidence relates to the percentage of all samples which can contain a true population variable. It is calculated by a random sampling of the population and is often linked with a certain level of confidence, which would be a probability, usually a percent. The 90% say that the true mean will be 90%, but 10% won't.

The Z-score needs to be measured, measured from percentage points away from the mean in statistics of a value related to the mean (which is to say, the average) of one sequence of items.

The time in days is 53 days.
