Self-study
A clothing manufacturer reports that unsalable garments, those found to be defective by inspectors plus those returned by retailers, total 7 percent of the garments produced. ████████ ██ ███████ ████ ███ ██ ███ █████████ ████████ ███ ████████ ██ ██████ ███ ███ ██████████ ██ ████████ ████████ ██ ████████ █████ ██ █ ████████
"Surprising" Phenomenon
Why is the percent of garments reported as recycled scrap 9% even though the percent of garments considered unsalable, which are all included in the garments recycled as scrap, is 7%?
Objective
The correct answer should differentiate between the category “garments reported as recycled scrap” and “garments considered unsalable” in a way that would lead the recycled scrap % to be higher. For example, maybe there are additional items that are part of garments reported as recycled scrap besides just garments considered unsalable.

Which one of the following, ██ █████ █████ ██████████ ████ ██ ██████████ ███ ███████████ ███████ ███ ████████ ████████████
a
Garments with minor █████████ ███ ████ ██ █████████ ███████ ███ ████ ██ ██████████ ██████ ███ ███ ███ ████████ ███ ██████████
If garments aren’t recycled, then they aren’t considered unsalable either, because everything unsalable is part of recycled scrap. So, this tells us about garments that aren’t part of either the recycled category or unsalable category. This has no impact.

The percentage of ████████ ████████ ██ ██████ ███████ ██ █████████ █████████ ██ ████████ ██ █████████ ████████████ ████████ ██ ████████████ ██████ ██ ███████
We already know that all unsalable garments are part of the garments recycled as scrap. Additional details about what kinds of garments are unsalable doesn’t add any relevant information.
c
Some inspectors, in █████ ██ ██████ ████ ██████████ ████ ██ ██████████ ████████
Unsalable garments include those reported by inspectors as defects. The actual defects don’t matter; only the reported defects. So overreporting of defects doesn’t impact the comparison between unsalable garments and recycled garments.
d
The total number ██ ████████ ████████ ██ ███ ████████████ ███ █████████ ████████ ████ ███ ████ █████
The stimulus never compared stats across different years, so this information doesn’t impact the comparison between unsalable garments and recycled garments.

Unsalable garments are ████████ ██ ██████ ███ ████████ ████████ ███ ████████ ██ ███████
The % of unsalable garments is calculated in a different way compared to the % of recycled garments. This could account for why the first figure was 7% and the second was 9%. The garments considered unsalable (and sent to recycling) could be heavier than other garments.
