Final answer:
A brand manager concerned about brand B's low attitude score implies potential issues with the brand's market perception, requiring strategic adjustments. Ethical issues in market research can skew data reliability, necessitating measures to guarantee impartiality and accurate representation of findings. For testing brand preference, a binomial distribution would be appropriate.
Step-by-step explanation:
The brand manager's concern regarding brand B's attitude score is likely related to how the score reflects the consumers' perceptions and feelings towards the brand. If we compare choice B with choice D, we realize that choice D implies that the attitude score does not correlate with sales, suggesting it is of no concern to the brand manager focused on financial performance.
On the other hand, choice B suggests the attitude score is lower than expected, which could be a more immediate concern for the brand manager, indicating a potential problem with the brand's image or the marketing strategy that needs addressing. In this context, choice B reflects an issue that directly impacts the brand's position in the marketplace and the manager's strategic decision-making.
When considering the unethical behavior in research data, the reliability of the resulting data could be compromised. If a brand sponsors a study and incorporates biases such as selective product ranges or visibility of brands during sampling, the data may not accurately represent the true preferences of the consumers. Correcting these biases involves ensuring impartiality and anonymity in studies and accurately representing study findings in commercial references. For a hypothesis test regarding preference for a brand in a taste test, the binomial distribution would be suitable since the outcome is categorical and binary (preferred Brand A or did not prefer Brand A).
