The study in Exercise 18.5 compared individuals who have Highly Superior Autobiographical Memory (HSAM) with control individuals without this ability. Participants were asked to take a verbal association test. Here is the Crunchit! output for the two-sample t test asking whether individuals with HSAM score significantly higher than control individuals on such a measure of verbal association Null hypothesis: Difference of means = 0 Alternative hypothesis: Difference of means > 0 n Sample Mean Std Dev HSAM 9 3.444 2.506 CON 18 3 2.301 df: 14.92 Difference of means : 0.4444 t statistic: 0.4463 P-value: 0.3309 18.13 What is the value of the test statistic for this two-sample test? a. 0 b.0.4463 c. 12.92 18.14 From the two-sample r test we conclude that a. individuals with HSAM have significantly greater abilities on verbal association tests than non- HSAM individuals, on average. b. individuals with or without HSAM have the same abilities on verbal association tests, on average. c. the study failed to find significant evidence that, on average, individuals with HSAM have greater abilities on verbal association tests than non-HSAM individuals.
