Find the following:

1. Using the provided figure, plot the time needed each activity and determine the critical path.

2. Total completion time (in days).

3. If the project will start on July 1, 2023, when will be the completion date?

Critical path identification: In the table below are the activities of a certain engineering project and time (in days) n activities. Early Start (ES): It is equal to the Early Finish to the activity's precedent. If it has more than one precedent, the highest value is taken. Early Finish (EF): It is equal to the Early Start of the activity plus its duration (t). EF = ES + t. Late Start (LS): It is equal to the Late Finish minus its duration (t). LS = LF - t. Late Finish (LF): It is equal to the late start of the activity that follows. If it has more than one successor, the lowest value is taken. Slack (S) or Total Float: It can be calculated in two ways. S = LS - ES = LF - EF. Activities with zero slack make up the critical path and are highlighted in green. Free Float: Is measured by subtracting the early finish (EF) of the activity from the early start (ES) of the successor activity. Represents the amount of time that a schedule activity can be delayed without delaying the early start date of any immediate successor activity within the network path
