Question
In a bank, the drive-in window is serviced by one teller, the data analysis led to
the conclusion that: Inter-arrival times: exponentially distributed with rate A =
45/hour, and Service times: Normal(1.1, 0.22). Consider that 51 be the true mean
value u0 = 51. There were 6 statistically independent replications of the model,
each of 2-hour duration, and as in the following table.
%3D
(Replication, Arrival/arrival) : (1, 50), ( 2 , 50) (3, 50) , (4 , 49), ( 5 ,49), (6 , 51)
Compute the sample mean.
