You may need to use the appropriate technology to answer this question.Consider the PERT/CPM network with estimated times in weeks shown in the following figure. The project is scheduled to begin on May 1.StartABсDEFGH1.0The three-time estimate approach was used to calculate the expected times and the following table gives the variance for each activity.Activity Variance0.41.10.70.40.70.7A11.1B3E1D2C4F23T7Finish(a) Give the expected project completion date and the critical path. (Enter your critical path as a comma-separated list.)The expected project completion isweeks from May 1 with a critical path of(b) Based only on the critical path, by what date are you 99% sure the project will be completed? (Round your answer to one decimal place.)weeks from May 1.

Find the given details below: ActivityVarianceDuration(Weeks)A11B0.43C1.14D0.72E0.41F0.72G0.73H1.17Forward Pass CalculationWe move from left to rightForward pass for activities calculates 2 values - Earliest Start (ES) and Early Finish (EF)ES for starting activities is always 0.EF = ES + DurationFor other activities, other than the starting activities, the ES is the maximum of the EF of its preceding activitiesBackward Pass CalculationWe move from right to leftBackward pass for activities calculates 2 values - Latest Start (LS) and Latest Finish (LF)LF for last activity is always same as its EF.LS = LF - DurationFor other activities, other than the starting activities, the LF is the minimum of the ES of its succeeding activitiesThe network diagram shows the precedence relationships, forward pass and backward pass:Critical Path is the path of activities which has equal values of LS and ES. Also, it has equal values for EF and LF.The highlighted arrows connecting the activities shows the critical path activities.Critical Path is A,B,D,G,HDuration of the project is the duration of the critical path activities = 1+3+2+3+7 = 16 weeks.The critical path duration is 16 weeks.Let Scheduled time= x weeksProject Duration =16 weeksProject variance will be the sum of the variance of the activities on the critical path i.e. A,B,D,G,HProject Variance = 1.0+0.4+0.7+0.7+1.1 = 3.9Table value of z from the normal distribution table = 2.32Use the following formula:The project will be completed with 99% surety in 20.6 weeks from May 1.Find the answers below:a) The expected project completion is 16 weeks from May 1 with the critical path of A, B, D, G, Hb) The project will be completed with 99% surety in 20.6 weeks from May 1.
