Q2: Under the assumptions that the completion time of the project is normally distributed with mean u and standard deviation o find: A: The probability of completion in 194 days B: The probability that the completion times lies within 2.5 confidence interval that we are reasonably sure the completion date lies within. C: The probability of completion in 180 days. D: The probability of completion time is larger than 210 days. E: Provide a completion time that has only 1 % chance to be exceeded
