An activity has an optimistic time estimate of 25 days, a most likely estimate of 29 days, and a pessimistic estimate of 34 days. What is the expected duration of the activity

The expected duration of the activity is 29 days and 4 hours.

Step-by-step explanation:

Step 1:

The optimistic time, = 25 days,

The most likely estimate, = 29 days.

The pessimistic time, = 34 days.

According to PERT, the expected duration of the activity,

Step 2:

By substituting the given values, we get

0.1666 days =

29.1666 days approximately equal 29 days and 4 hours.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
