The expected number of lost calls per hour are:
= zero.
Explanation:
a) Data and Calculations:
Number of sales department telephone lines = 3
Number of persons taking sales calls = 1
Average completed sales profit = $70
Average calls per hour over the last 6 months = 6
Time required by the sales rep to service a call and complete the sale = 3 minutes
Number of calls that the sales rep can service in 1 hour = 20 (60/3)
Expected number of lost calls = Average calls per hour minus number of calls that the sales rep can service per hour
= 6 - 20 = -14
This means that the sales rep has opportunity to answer 14 more calls within the hour but only 6 calls are received. Therefore, there are no lost calls.
