Education influences attitude and lifestyle. Differences in education are a big factor in the "generation gap." Is the younger generation really better educated? Large surveys of people age 65 and older were taken in n1 = 36 U.S. cities. The sample mean for these cities showed that x1 = 15.2% of the older adults had attended college. Large surveys of young adults (age 25 - 34) were taken in n2 = 39 U.S. cities. The sample mean for these cities showed that x2 = 19.5% of the young adults had attended college. From previous studies, it is known that ?1 = 6.6% and ?2 = 5.8%. Does this information indicate that the population mean percentage of young adults who attended college is higher? Use ? = 0.05.
