Q3.1.- In this environment, what is the upper capability measure of the cashier transaction times?

Q3.2. - What is the current probability of missing the efficiency standard limit?

Q3.3 - A project team in a small bank is studying the productivity of the cashier operations.

Technical variability in transaction (deposit/withdrawal) times is identified as a potential area for improvement. The average time for such a transaction is currently normally distributed with mean 2 minutes and standard deviation 50 seconds. An "efficiency standard" has been laid down that transactions should not exceed 3.5 minutes. If the transaction completion process was upgraded and the upper capability measure (Cpu) of the transaction times was equal to 1.25 instead, what would be the probability of missing the efficiency standard limit?
