The contact centre is open seven days a week. Select all the days when the call volume averaged >100 per hour.

Steps to Solve

1. Identify the call volume data ranges Determine which ranges of call volumes are specified in the given data:

• 25 - 49 calls: Occurred from the 1st to the 6th of the month.
• 50 - 74 calls: Occurred for 15 days following the 6th.
• 75 - 100 calls: Occurred on the 22nd, 24th, 27th and last week of the month.
• Greater than 100 calls: Occurred on all remaining days.

2. List the days for each volume category Identify the specific days each volume category applies to:

• From the 1st to the 6th: 1, 2, 3, 4, 5, 6 (25 - 49 calls)
• The following 15 days after the 6th: 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21 (50 - 74 calls)
• Specific days for 75 - 100 calls: 22, 24, 27, and any days in the last week (22, 23, 24, 25, 26, 27)
• All remaining days will have >100 calls.

3. Determine the days with >100 calls The days not covered in the previous categories (days with calls averaging >100) are:

• After day 21, the applicable days are 22 (75-100), 23 (100+), 24 (75-100), 25 (100+), 26 (100+), 27 (75-100). Therefore, the remaining days with >100 calls are:
• 22, 23, 24, 25, 26, 27.

4. Compile a complete list of days with >100 calls Now compile the days based on the volume ranges:

• Days with >100 calls are: 23, 25, 26, and 27.
