Consider the office renovation project data in the following table. 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. Refer to the standard normal table ​(Make sure to round all intermediate calculations for te and variance to two decimal​ places.)   The probability is

The CEO of Carol O'Lights Manufacturing, produces custom-built relay devices for auto makers.  The most recent project undertaken by Ms. O'Lights requires 11 different activities. The activities necessary to build an experimental relay model and related data are given in the following table.   What is the Late Start on Activity C? What is the slack on Activity C? What is the slack on Activity B? What is the critical path? What is the Early Finish on Activity H?
