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 a 20% chance of on-time completion. (Use NORMAL CURVE AREAS table in APPENDIXI of the textbook.) from 112.45 to 112.57 days from 112.57 to 112.69 days from 112.09 to 112.21 days from 112.21 to 112.33 days from 112.33 to 112.45 days 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 a 39% chance of on-time completion. (Use NORMAL CURVE AREAS table in APPENDIXI of the textbook.) from 120.38 to 120.5 days from 120.74 to 120.86 days from 120.62 to 120.74 days from 120.5 to 120.62 days from 120.86 to 120.98 days To find the area under the normal curve, you can apply either Table I.I or Table 1.2. In Table 1.1, you must know how many stan. dard deviations that point is to the right of the mean. Then, the area under the normal curve can be read directly from the normal table. For example, the total area under the normal curve for a point that is 1.55 standard deviations to the right of the mean is 93943 . As an altemative to Table L.1. the numbers in Table 1.2 represent the proportion of the total area away from the mican, , to one
