Question
Ross Hopkins, president of Hopkins Hospitality, has developed the tasks, durations, and predecessor relationships in the following table for building new motels ime (weeks mmediate ime (weeks Immediate Activity a Predecessors Activity a m b Predecessor(s) 23 18 14 4 14 D, G, H 21 C, E a) The expected (estimated) time for activity C is 13.67 weeks. (Round your response to two decimal places.) b) The variance for activity C is 2.78 weeks. (Round your response to two decimal places.) c) Based on the calculation of the estimated times, the critical path is A-C-F-H-J- K d) The estimated time for the critical path is 44 weeks. (Round your response to two decimal places.) e) The activity variance along the critical path is 13.63 weeks. (Round your response to two decimal places.) f) The probability that Hopkins Hospitality will finish the project in 42 weeks or less isEner as a probability and round your response to three decimal places.)Explanation / Answer
F.
To complete the project in 42 weeks or less,
Z = (42-44)/SD
SD = 13.63^.5 = 3.69
Z = (42-44)/3.69 = -.54
Area covered at this value of Z =.2946 or 29.46% ( as per normal distrbution table)
So, there is 29.46% probability that project will be competed in 42 weeks or less.
