Question

Speedy Swift is a package delivery service that serves the greater Atlanta, Georgia metropolitan area. To maintain customer loyalty, one of Speedy Swift's performance objectives is on-time delivery. To monitor its performance, each delivery is measured on the following scale: early (package delivered before the promised time), on-time (package delivered within 5 minutes of the promised time), late (package delivered more than 5 minutes past the promised time), lost (package never delivered). Speedy Swift's objective is to deliver 99 percent of all packages either early or on-time. Another objective is to never lose a package.

B.)

(b) Construct a frequency table for delivery performance for last month.

Performance ___Frequency

Early ____________23

On-time _________ 68

Late _____________8

Lost _____________ 1

C)

Performance ___Frequency ___R/frequency

Early ____________23 ___23/100 = 0.23

On-time _________ 68 ___68/100 = 0.68

Late _____________8 ____8/100 = 0.08

Lost _____________ 1 _____1/100 = 0.01

D)

Percentage (%) Packages either early or on time :

(0.23 + 0.68) = 0.91 = 91

Late packages (%) = 0.08 = 8

Lost packages (%) = 0.01 = 1
