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. Click the icon to view the table. a. Based on the critical path, find the probability of completing the office renovation project by 40 days. Refer to the standard normal table. (Make sure to round all intermediate calculations for to and variance to two decimal places.) The probability is (Enter your response rounded to four decimal places.) b. Find the date by which you would be 80 percent sure of completing the project. Refer to the standard normal table. One is 80 percent sure the project will be complete in days.
