Question 31

The advertisement was effective in building brand awareness.

The study demonstrates a 95% confidence that the subjects exposed to the advertisement exhibited increased brand awareness compared to those who were not shown the advertisement. This indicates a strong correlation between advertisement exposure and brand recognition.

A) Five percent of the subjects did not like the advertisement.

This option is incorrect because the data focuses on brand awareness rather than individual preferences regarding the advertisement itself. The study does not provide information about subjects' likes or dislikes.

B) Ninety-five percent of the subjects liked the brand.

This option is misleading as it interprets the 95% confidence level incorrectly. The study indicates that there is a high confidence that brand awareness was achieved, but it does not specify how many subjects liked the brand or make any claims about their personal preferences.

C) The advertisement was effective in building brand awareness.

This statement accurately reflects the findings of the study, as there is a significant level of confidence that the advertisement succeeded in enhancing brand awareness among the subjects who viewed it compared to the control group.

D) The advertisement was effective in increasing sales.

This option cannot be concluded from the study's data, as it specifically addresses brand awareness rather than direct sales figures. The effectiveness of the advertisement in terms of sales is not covered by the research presented.

Conclusion

The correct answer, that the advertisement was effective in building brand awareness, is substantiated by the study's findings that show a significant difference in awareness levels between the groups. In contrast, the other options either misinterpret the data or address aspects outside the study's scope, reinforcing the validity of the correct conclusion.
