A social psychologist recently developed a childhood memories test that is intended to measure how people recall pleasant and unpleasant memories from childhood. Scores on this test range from 1 (very unpleasant) to 100 (very pleasant). The psychologist standardized the test with a very large group of college students (ages 18-25), and the means score was μ = 60. The test was then given to a sample of N = 25 individuals who were all between the ages of 40 and 45. The average score for this sample was = 64.3 with s = 4.9. Does this sample provide sufficient evidence to conclude that childhood memories for older adults (ages 40-45) are significantly more pleasant than memories for college students? Use a one-tailed t-test with α = .05 (include all elements as detailed in t-Test Handout).
