Estimation

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

Consider the office renovation project data in Table 7.16. A
“zero” time estimate means that the activity could take a very
small amount of time and should be treated as a numeric
zero in the analysis

a. Based on the critical path, find the probability of
completing the office renovation project by 39 days.
b. Find the date by which you would be 90 percent sure of
completing the project.
