17. The distribution that you use for networks in project times is known as considering probability of three A. Normal distribution B. Exponential distribution C. Binomial distribution D. Negative exponential distribution E. None of the above 18. T he biggest advantage/advantages of the exponential smoothening method of forecasting is/are A. No waiting period is required and not a large data is required even then reasonably good forecas can be calculated. B. It includes the benefits of time series analysis of forecasting as it belongs to this category C. The value of alpha (smoothing constant) can be made to change or adapt to changed circumstances. D. All of the above E. Only A and B The important disadvantage/disadvantages of MBO as observed are: A. Time and paper work involved B. Supervisor just assigns and does not negotiate C. It leads to Gamesmanship of subordinates DIT does not avoid the tendency of subordinates to focus on relatively few goals E. All of the above 19. 20. Position, recognition, status and respect are associated with which need A. Physiological need 8. Security/safety need C. Social/affiliation need D. Esteem need E. Self-actualization need

Solution

17.

Normal Distribution, this is the distribution which covers 3 times std deviation on each side of the mean to cover the whole spread of the distribution.

Hence: Option A

18.

A and B are correct.

As it is a time series it has all its properties and it uses the last periods value to forecast, hence option A

Option E

19

Al of these are correct, as in case of MBO

Hence option E

20

As per the maslow\'s need hierarchy, all these are part of need and recognition and hence is esteem needs.

Hence option D
