Answer:
Difference = 0.8 customers per day
Step-by-step explanation:
The period under consideration for both calculations is 5 days
Current Month:
- Mean number of customers = 17 per day
Following month:
- 16 customers per day for 4 days = 16 x 4 = 64 customers
- 25 customers served on 5th day
- Total customers for 5 days = 64 + 25 = 89
- Mean number of customers = 89/5 = 17.8 per day
Difference = 17.8 - 17 = 0.8 customers per day
