Q.35-In the solution also it has taken as 450 rpm only. The given answer is based on 450 rpm but not on 4.5rpm. Check it.

Q.18 answer as normal distribution is right. In PERT analysis activity time follows a Beta distribution curve while the project expected time (this is for entire project and not for each activity separately) follows normal distribution curve. The question says completion time, which means the completion time for the entire project and hence normal distribution is right. Beta distribution curve represents the activity-time frequency distribution. For more verification please refer Operation Research by Hira Gupta page no. 1190.
