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 = 31 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 = 38 U.S. cities. The sample mean for these cities showed that x₂ = 18.2% of the young adults had attended college. From previous studies, it is known that σ₁ = 7.6% and σ₂ = 4.8%. Does this information indicate that the population mean percentage of young adults who attended college is higher? Use α = 0.05.
