One of the very useful tools in project management analysis is the PERT and CPM.
PERT (Program evaluation and review technique) provides valuable information regarding which activities need to be closely watched.
While CPM (Critical Path Method) helps in determining the time required to complete each task, and the minimum time required to complete a project.

Answer:
Standard deviation= $43.309
Explanation:
Standard deviation can be defined as a measure of dispersion of a set of values from their mean. When standard deviation is low it means the variables are close to their mean. While if standard deviation is high the variables are far away from the mean.
The mean= (sum of the values)/number of values
Mean= (97+102+56+26+3)/5
Mean= $56.80
Standard deviation= √(Σ(x- mean)^2/number-1
Standard deviation= √{(97-56.8)^2+ (102-56.8)^2+ (56-56.8)^2+ (26-56.8)^2+ (3-56.8)^2}/5
Standard deviation= √(1616.04+2043.04+0.64+948.64+2894.44)/5-1
Standard deviation= √7502.8/4
Standard deviation= $43.309

The correct answer is b) "Time is money"
Explanation:
The Opportunity costs refer to all the benefits that a person, investor or company misses out on when they deciding one alternative over another.
For example, the expression "time is money" means that you can´t waste time because you could use this time to produce money. In other words, the time that you expend in some activities different than a profitable activity, are money that you won't recuperate. This is a clear example of opportunity cost when you choose an alternative that has fewer benefits than others.
