Final answer:
The unethical behavior in this case includes a conflict of interest, limited options, bias, and manipulation. These factors can impact the reliability of the resulting data and should be corrected.
Step-by-step explanation:
The unethical behavior in this case is a combination of factors:
- The survey being commissioned by the seller of a popular brand of apple juice creates a conflict of interest, as the company has a vested interest in promoting its own brand.
- The inclusion of only two types of juice (apple juice and cranberry juice) limits the options for the participants and may not accurately represent their preferences.
- Allowing participants to see the brand of juice during the taste test introduces bias, as it may influence their perception and preference.
- Brand X referencing the study in a commercial and claiming that most teens prefer it over Brand Y is a manipulation of the data to promote their brand.
These unethical practices can significantly impact the reliability of the resulting data as they introduce biases, conflicts of interest, and manipulation. To correct the problem, the survey should be commissioned by an impartial party, include a wider range of fruit juices, and the participants should be blinded to the brand during the taste test to ensure unbiased results.
