Calculate duration estimates for the following situation:

The operations manager was in the process of upgrading the IT network and preparing estimates from the technology installers in regards to how long the existing network would be down during the upgrade. The technologists believed that it could be done within 8 days if everything went according to plan. There is the possibility it could take up to 16 days if they ran into hardware difficulties. The operations manager asked if there was any way to decrease the number of days. The technologists thought that if they focused all resources, they could be done in as soon as 6 days. Using the beta distribution method, what is the estimated time to complete this task?
