5. There are 12 tasks that need to be performed to complete a project. The mean and standard deviation of the 12 tasks are in the following table (hours): Task Mean Standard Deviation : 5 Question 8. 3 2 0 12 4 3 2 [=1 5 5 3 6 6 l 8 3 l ( _ ) 9 2 l 10 5 2 ll 4 2 l2 3 0 Assuming that no task can be completed in parallel, what is the probability that the project can be completed Within 53 hours? Assume that n = 12 is large enough for CLT. Let X1,X2, ,Xlz be the 12 tasks
