Question

A survey shows: 65% of tobacco users were advised to stop. Also, 3 out of 10 tobacco users attempted to stop. Based only on this data, which statement can be inferred with certainty?

• A. A majority of tobacco users who were advised to stop consuming tobacco made an attempt to do so.
• B. A majority of tobacco users who were advised to stop consuming tobacco did not attempt to do so.
• C. Approximately 30% of tobacco users successfully stopped consuming tobacco.
• D. Approximately 65% of tobacco users successfully stopped consuming tobacco.

Hint:

In logical inference questions, focus on what is explicitly given. Do not infer success or outcomes unless stated. Here, only attempts vs advice percentages allow a definite conclusion.

Answer 1

The Correct Option is B

Step 1: Translate the information.
- \(65%\) of users were advised to quit. - Only \(30%\) (3 out of 10) attempted quitting.

Step 2: Link the groups.
All attempts (30%) must come from the "advised" group (65%), because only those advised can be expected to attempt. So, among those advised (65%), only 30% attempted.

Step 3: Majority check.
Since 65% were advised but only 30% attempted, the remainder (35%) did not attempt. Thus, within the advised group, more than half did not attempt quitting.

Step 4: Eliminate wrong options.
(A) Claims majority of advised did attempt — false. (C) and (D) talk about successfully quitting, but success data is not given — cannot infer. Only (B) follows with certainty.

Final Answer:
\[ \boxed{\text{(B)}} \]
