A psychologist examined the effect of chronic alcohol use/abuse on memory. In this experiment, a typical test of memory was used, because its scores are standardized. Scores from the general population form a normal distribution with µ = 50 and s = 6. A sample of n = 22 alcohol abusers is given the memory test and the mean of that sample is 47. Which statistical test would you use to examine if alcohol abuse has a statistically significant effect on your memory? a. One-sample t-test b. Two-sample (independent sample) t-test c. Repeated measures t-test d. Analysis of Variance (ANOVA)
