 A researcher (not coincidentally a psychologist) hypothesizes that Psychology majors have

greater

Need for Cognition (NFC) than do business majors. Using a random sample of 101 Psyc majors and 101 Business majors, she administers the Cacioppo et al NFC scale (where higher scores represent a greater need for cognition). For the sample of Psyc majors, M = 43, SD = 6.  For a sample of Business majors, M = 38, SD =4.5. At the α =  .01 level, what should this researcher conclude?
