Question

a researcher tracks data about the outgoing mail in a large office. you want to complete the two-way frequency table to show the researcher’s results. complete parts a and b. a. complete the two-way frequency table to show the researcher’s results. table: type of delivery (regular, overnight, total); type (letter, package, total); letter overnight=5, package regular=25, package total=35, total total=55; smaller table with same structure

Explanation:

Step1: Find Overnight Package

For Package, Total = Regular + Overnight. So Overnight (Package) = Total (Package) - Regular (Package) = \( 35 - 25 = 10 \).

Step2: Find Total Overnight

Overnight total = Overnight (Letter) + Overnight (Package) = \( 5 + 10 = 15 \).

Step3: Find Total Letter

Total (Letter) = Total (All) - Total (Package) = \( 55 - 35 = 20 \).

Step4: Find Regular Letter

For Letter, Total = Regular + Overnight. So Regular (Letter) = Total (Letter) - Overnight (Letter) = \( 20 - 5 = 15 \).

Step5: Find Total Regular

Total (Regular) = Regular (Letter) + Regular (Package) = \( 15 + 25 = 40 \).

Now fill the table:

Type	Regular	Overnight	Total
Package	25	10	35
Total	40	15	55

Answer:

The completed two - way frequency table is as follows:

Type	Regular	Overnight	Total
Package	25	10	35
Total	40	15	55
