Understanding the Printer Page Data

The question asks us to analyze the provided table which shows the number of pages printed by five different printers, labeled A through E, over five days, from Monday to Friday. Our goal is to find out which printer printed the third lowest total number of pages when considering all five days together.

To solve this, we need to calculate the total number of pages printed by each printer over the entire week (Monday to Friday). We will sum the pages printed each day for each printer.

Calculating Total Pages for Each Printer

Let's calculate the total pages for each printer using the data from the table:

• Printer A Total: To find the total pages for Printer A, we add the pages printed each day: $\text{Total}_A = 25 + 40 + 22 + 32 + 36 = 155$ pages.
• Printer B Total: For Printer B, the total is: $\text{Total}_B = 20 + 15 + 11 + 42 + 36 = 124$ pages.
• Printer C Total: For Printer C, the total is: $\text{Total}_C = 35 + 30 + 33 + 32 + 37 = 167$ pages.
• Printer D Total: For Printer D, the total is: $\text{Total}_D = 15 + 20 + 40 + 30 + 35 = 140$ pages.
• Printer E Total: For Printer E, the total is: $\text{Total}_E = 25 + 20 + 20 + 22 + 25 = 112$ pages.

Comparing Total Printer Pages

Now we have the total number of pages printed by each printer over the five days:

• Printer A: 155 pages
• Printer B: 124 pages
• Printer C: 167 pages
• Printer D: 140 pages
• Printer E: 112 pages

To find the third lowest number of pages, we need to arrange these total page counts in ascending order (from lowest to highest):

112 (Printer E), 124 (Printer B), 140 (Printer D), 155 (Printer A), 167 (Printer C)

Let's list them out clearly:

1. Lowest: 112 (Printer E)
2. Second Lowest: 124 (Printer B)
3. Third Lowest: 140 (Printer D)
4. Fourth Lowest: 155 (Printer A)
5. Highest: 167 (Printer C)

Identifying the Printer with the Third Lowest Total

Based on the sorted list, the third lowest number of pages printed is 140 pages. This total corresponds to Printer D.

Therefore, Printer D printed the third lowest number of pages in all five days taken together.

Additional Information - Data Aggregation and Sorting

This problem involves two main steps in data analysis:

1. Data Aggregation: We summed the daily page counts for each printer to get a total count over a period (five days). This process of combining data points to get a summary or total is called aggregation. In this case, we aggregated data by printer.
2. Data Sorting: Once we had the total page count for each printer, we needed to find the third lowest value. This required sorting the aggregated totals in ascending order. Sorting data helps us easily identify minimums, maximums, and values at specific positions (like the third lowest).

Understanding how to aggregate data (like finding sums, averages, or counts) and how to sort data are fundamental skills in data interpretation and quantitative analysis.
