Question

As a researcher, you want to know if reaction times change following consumption of alcohol. You obtain a random sample of 150 college students (age 21+). At baseline, you measure their reaction time on a task that requires them to press a button each time they hear a specific sound. Baseline reaction time is measured at 0.89 seconds (s = 0.15). After consuming a specified amount of alcohol, you ask them to repeat the reaction time test. This time, reaction time is recorded with a mean of 1.03 seconds (s = 0.23). Which test would you use to determine if the students' reaction time was significantly different following the consumption of alcohol? a. Odds Ratio b. One-sample t-test c. One-sample z-test d. Paired sample t-test e. Relative Risk f. Correlation/Simple Linear Regression g. One-Way ANOVA h. Independent Samples t-test
