6. Dr. Stoned wishes to know if giving students Valium during a statistics exam influences their grade. She recruits 50 undergraduate students from the statistics course that she teaches. She gives half of her participants Valium and she gives the other half a placebo pill just before they take their final exam. The average grade for students who took Valium was 82.5, and the average grade for students who took the placebo pill was 78.5. The estimated standard error of the mean for the two samples was 4.3. What type of statistical test you should conduct?
