Question: According to the 2010 U.S. Census, 11.7% of the people in the state of Oregon were Hispanic or Latino. A political party wants to know how much impact the Hispanic and Latino vote will have, and wonder if that percentage has increased since then. They take a random sample of 853 adults in Oregon and ask, among other things, their race. They found that 113 of the people surveyed were Hispanic or Latino. At a 0.05 significance level, can the political party conclude that the Hispanic proportion of the population in the state of Oregon has increased since 2010?
