Q.1 On average, 10 customers are expected to arrive at a salon every hour, of which 66.67% request haircut and rest request hair coloring. Given that only a few standard styling options are offered, it is estimated that: Customers who request haircut will spend, on average, a total of 27 minutes in the salon, whereas customers who request hair coloring will spend, on average, a total of 36 minutes in the salon.

What is the average number of customers in the hair salon?

Q.2 The provided information is sufficient to say that on average 1.5 customers will be in the system. True or false?

Q.3 If the utilization halves (i.e., becomes 30% instead of 60%), the average wait time for a customer in the queue will also decrease by half. True or false?

Q.4 Further, due to space constraints (or, to maximize the use of super-expensive retail space), the size of bathroom in each room of this hotel at Times Square in New York City is significantly smaller than one would expect. During check-in itself, the hotel staff says to the guest, We hope you enjoy the wonderful view of Times Square from your room. Also, note that the size of bathrooms in our hotel is a bit smaller, but we are sure that the superb view and other amenities will make up for it. What is the concept behind including this statement in the service delivery?

Please answer all questions clearly. I will thumbs up if answers make sense, thank you for the help!!!!
