Final answer:
The average estimate for completing the task using the triangular estimate is approximately 59.17 days.
Step-by-step explanation:
The triangular estimate is a technique used to find the average estimate for a task with different completion times. To find the average estimate, we take the weighted average of the best case, worst case, and most likely case scenarios. In this case, the best case scenario is 55 days, the worst case scenario is 70 days, and the most likely case is 60 days.
To calculate the average estimate, we use the formula:
Average Estimate = (Best Case + 4 x Most Likely Case + Worst Case) / 6
Substituting in the values:
Average Estimate = (55 + 4 x 60 + 70) / 6 = 59.17 days
So, the average estimate for completing the task using the triangular estimate is approximately 59.17 days.
