MAT 510 – Homework Assignment
Homework Assignment 5
Due in Week 6 and worth 30 points
The data in below table lists country code and the order to
remittance (OTR) time for hardware / software installations for the
last 76 installations (from first to last). OTR is the time it
takes from an order being placed until the system is installed and
we receive payment (remittance). Because this company does business
internationally, it also notes the country of installation using a
country code. This code is listed in the first column.
