A psychologist examined the effect of chronic alcohol 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 σ = 6. A sample of 22 alcohol abusers is given the memory test and the mean of that sample is x̅ = 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 t test c. repeated measures t test d. ANOVA
