A social psychologist wants to investigate whether stereotypes can be used to achieve positive outcomes. To explore this, the researcher randomly assigns 9 females to one condition in which participants were primed with a positive stereotype where they were asked to read a paragraph reminding them that Asians are stereotypically believed to be good at mathematics. Another 9 participants were primed with a neutral paragraph stating that many individuals find mathematics difficult and that many overcome this difficulty by focusing on the task at hand. After reading their assigned paragraph, both groups then completed a series of timed mathematical tasks. Adopting a significance or alpha-level of 5% (i.e., .05 probability), what is the two-tailed critical t value cut-off for this study? ±2.120 ±2.307 ±2.263 ±2.110
