Hi MartyMurray KarishmaB

In the choice C: The percentage of surveyed readers who like the format change was almost the same as the percentage of the entire potential readership who would like format change-->We don't know the the actual number of surveyed readers who liked the format,we only know the percentage of those who returned the survey.
How can we compare this with the actual potential readers ?

Kindly help
Thanks !

In option (C) "surveyed readers" means the ones who returned the forms. A company sends out the form to all its readers and if 500 return the form, it means there are 500 surveyed readers. All readers are not surveyed readers.

You're confusing response rate with representativeness. These are completely different concepts!

Let me clarify with a simple example:

Imagine surveying 100 people about ice cream flavors:
• Scenario 1: Only 20 people respond (20% response rate)
• Scenario 2: 90 people respond (90% response rate)

What matters is NOT how many responded, but WHETHER those who responded represent everyone!

Option C tells us: The 62% who support the change among respondents = approximately 62% support among ALL potential readers

This means:
✓ If 20% responded and they're representative → we can trust the 62% figure
✓ If 90% responded but they're NOT representative → we CANNOT trust the 62% figure

Think of it this way: You're at a party with 100 guests. You ask 10 random people if they like the music. If those 10 are truly representative (mix of ages, tastes, etc.), their opinion reflects the room - even though you only asked 10%!

Therefore: Option C strengthens by confirming representativeness, NOT by telling us the response rate!

Note that Option A (which mentions 90% response rate) is incorrect precisely because high response rate ≠ representative sample!

Hope this clarifies!

For option C, Could you please explain why we do not consider the possibility that only say 20% of the survey takers actually returned the survey? Does that not mean that we do not know what the remaining 80% voted for?.
