Final answer:
Spooner targeted Iowans in promotional materials for their strategic importance in the promotional campaign, related to the historical use of posters for influencing public opinion among new voters. The Intel Corporation survey at the 'America's Smithsonian' event likely did not represent all demographic groups equally, as attendance at such events can be influenced by multiple factors. Therefore, sample statistics from this event may not reflect true population parameters.
Step-by-step explanation:
In Spooner's view, promotional materials targeted Iowans because of their strategic demographic importance for the promotional campaign. Understanding the expansion of suffrage and the socio-political need to influence new voters, as pointed out by Jeffrey Schnapp, entities such as the state, political movements, and labor unions required efficient ways to communicate with the masses. Posters and other materials became a key medium for achieving this, being highly visible in public spaces and serving as mechanisms for persuasion, information dissemination, and social cohesion. Additionally, Friedrich Engels recognized the power of posters as the 'main means of influencing the proletariat', capitalizing on their high visibility in everyday life.
Regarding the Intel Corporation's survey at the Los Angeles Convention Center during the 'America's Smithsonian' road show, it is unlikely that all demographic and ethnic groups were equally represented at the event. Factors such as geographical location, the nature of the event, and the interest of different communities in such an exhibition could have influenced the demographics of attendees, thereby affecting the representativeness of the survey with regard to the broader population.
The sample statistics from the event may not accurately reflect the population parameters because the subset of individuals who visited a specific event like 'America's Smithsonian' is not indicative of the entire population's demographics or perspectives. In essence, this selection bias limits the generalizability of the survey findings.
