2- Please I want answer with steps. Many thanks
Negative float Time refers to the time which is beyond the time taken in completion of the project task earlier projected.
Yes, it is possible for an activity to have a negative float time.
refer to float time, it is the time-delayed for a project without affecting the deadline of the project. But negative float time indicates the negative delay in completion of the project which affects the project deadline.
Therefore, this negative float time should be covered as fast as possible. It may be due to any scheduling problem also. Like if the project starting date has been set earlier of when it actually started, then its end date is also set prior to which it should have been set and it leads to negative float Time.
OR there are chances that there is some error in the production part that is delaying the completion of tasks at time. The errors should be checked and rectified as early as possible.
Therefore, it can be said that negative float Time is possible for a project.

- Limbo Technologies has embarked on another project that has an estimated completion time of 40 weeks and a standard deviation of 5 weeks. It is estimated that the project completion time is normally distributed. i)What is the probability of finishing the project in 38 weeks or less? ii)The due date for the project is set so that there is a 90% chance that it will finish by this date.

- Two new Internet site projects are proposed to a young start -up company. Project A will cost $250,000 to implement and is expected to have annual net cash flows of $75,000.

Using the payback period, which project is better, from a cash flow standpoint?Hi, I need help answering the last question. Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible.

- I also know answer is d, but please explain each and every option why other option are incorrect too. Which of the following statements regarding PERT analysis is true? Each activity has two estimates of its duration. Project variance is the sum of all activity variances. Project standard deviation is the sum of all critical activity standard deviations. Only critical activities contribute to the project variance. none of these is true.Answer all the following questions based on Table 2 (a) Feasibility studies for a project is an early study before the project begins.
