A project being analyzed by PERT has 55 activities, 8 of which are on the critical path. If the estimated time along the critical path is 125 days with a project standard deviation of 15 days, find the project deadline that gives this project an 80% chance of on-time completion. (Use NORMAL CURVE AREAS table in APPENDIX I of the textbook.)

Group of answer choices from 137.42 to 137.54 days from 137.66 to 137.78 days from 137.18 to 137.3 days from 137.54 to 137.66 days from 137.3 to 137.42 days
