Question 732334: he new director of special events at a large university has decided to completely revamp graduation ceremonies. Toward that end, a PERT chart of the major activities has been developed. The chart has five paths with expected completion times and variances as shown in the table. Graduation day is 17 weeks from now.
Use Table B.
Path Expected Duration
(weeks) Variance
A 11 1.20
B 11 2.20
C 14 1.03
D 18 2.79
E 15 1.50
Assuming the project begins now, what is the probability that the project will be completed before: (Round intermediate calculations to 2 decimal places and "Probability" values to 4 decimal places.)
a. Graduation time?
Probability for graduation time
b. The end of week 16?
Probability at the end of week 16
c. The end of week 14?
Probability at the end of week 14
