RESPOND EXERCISE A, B, C , D AND E

The estimated times and insnedute predecessors for the activities in a project at Howard Unrar's retinal scanning company are given in the following table Assume that the activity times are independent Time (weeks) immediate Time (weeks) m Activity a Predecessors Activity immediata Predecessor) m 6 10 10 12 11 16 6 D 4 . This exercise contains only parts a b c d and Based on the divity ime estimates, the expected times and variance for each of the activities are (round your response to two decimal plac Activity Expected Time Variance A B C D The expected completion time of the crtical path weeks pround your response to fadecimal pla The expected completion time of the path other than the coat weeks round your response to ho decimal p Theanance of the critical path weeks round your response to two decimal place in 231 as a probability and round your response to be decl the time to complete the acties on the non critical path is normally distributed, then the probability that the non critical path wil be finished in 23 weeks or less . 7 . b 13 12 Next
