Final answer:
The exact percentage increase in brand product purchase intentions among consumers who attend brand-sponsored events, as studied by the Advertising Research Foundation, is not provided. The importance of such events and similar marketing strategies like brand ambassadorships, in influencing consumer behavior, is well acknowledged in advertising research.
Step-by-step explanation:
The question pertains to a study conducted by the Advertising Research Foundation which investigated the impact of brand-sponsored events on consumer purchase intentions. However, the missing percentage to complete the statement provided in the original question is not given in the provided information. Studies like the one mentioned are common in marketing research where consumer behavior is observed in response to different advertising strategies such as brand ambassadorships, and attending brand-sponsored events. Brand ambassadorships, especially among college students involved in activities like sports and music, can significantly influence the purchase decisions of peers, underlining the effectiveness of such marketing strategies.
In a similar vein, conducting surveys and performing hypothesis tests, as mentioned in the examples involving a taste test for Brand A, a survey on big-time college sports programs, and an assessment of purchasing decisions, are techniques used in advertising research to gauge public opinion or behaviors. These methodologies help companies shape their marketing strategies to better appeal to their target demographics.
While the original question seems to be missing critical data to provide a precise percentage increase in purchase intentions, the implication is clear: participating in brand-sponsored events can considerably increase the likelihood of purchasing the brand's products.
