##### Q51. For beta distribution, the variance is given by

$\text { (a) } \frac{t_{P}-t_{O}}{2}$

$\text { (b) } \frac{t_{p}-t_{O}}{c}$

$\text { (c) }\left(\frac{t_{p}-t_{O}}{6}\right)^{2}$

$\text { (d) } \frac{t_{p}+t_{O}}{2} \text { . }$

Ans: $\text { (c) }\left(\frac{t_{p}-t_{O}}{6}\right)^{2}$

##### Q52. The deviation is the difference between

(a) mean time and the time under consideration
(b) the time under consideration and the mean time
(c) the time under consideration and optimistic time
(d) pessimistic time and optimistic time.

Ans:  (b) the time under consideration and the mean time

##### Q53. Variance is defined as the

(a) square of the deviation
(b) mean of the squared deviation
(c) square root of the deviation

Ans:  (b) mean of the squared deviation

##### Q54. The probability factor is given by the relation

$\text { (a) } Z=\frac{T_{S}+T_{E}}{2}$

$\text { (b) } Z=\frac{T_{S}-T_{E}}{6}$

$\text { (d) } Z=\frac{4 T_{S}+T_{E}}{6} \text { . }$

where TS = Scheduled time of completion, and TE = Earliest expected time of completion.

Ans:  $\text { (b) } Z=\frac{T_{S}-T_{E}}{6}$

(a) independent float
(b) free float
(c) total float
(d) interfering float.
