Question

The probability of completing a project in a specified amount of time is being calculated. For a particular path through the project, the ______________ shows the path’s number of standard deviations that the specified time is past the expected path completion time.

1) m-value
2) z-value
3) sigma-value
4) s-value
5) alpha-value

Answer 1

Answer: 2). z-value

Explanation: the z- value is a statistical tool used to measure the deviations of the standard deviation above or below the population mean,it can also be placed on a normal distribution curve.It used to calculate the probability of a value appearing within the normal distribution curve,it can also be used to determine the percentage of people participating in a given activity like the time it takes to complete a given task/ project by different persons.
