1) During busy times, 60 potential customers per hour arrive at the booth (assume a Poisson distribution). A booth worker takes 3.75 minutes, on average, to meet the information needs of a potential customer (assume an exponential distribution). How many booth workers are required for the average potential customer to spend no more than 5 minutes waiting and being served

Respuesta :

Answer:

Booth workers required = 4

Step-by-step explanation:

As given ,

Arrival rate = λ = 60 customers per hour

Time taken = 3.75 minutes

∴ we get

Average service rate = μ = [tex]\frac{60}{3.75}[/tex] = 16 customers per hour

Now,

Minimum numbers of booth workers required = [tex]\frac{60}{16}[/tex] = 3.75

As workers can not be in fraction

∴ Minimum number of booth workers required = 4
