A researcher would like to examine how the chemical tryptophan, contained in foods such as turkey, can affect mental alertness. A sample of n = 9 college students is obtained and each student’s performance on a familiar video game is measured before and after eating a traditional Thanksgiving dinner including roast turkey. The average score dropped by 14 points after the meal with SS = 1152 for the difference scores. Which statistical test would you use to determine if there is a significant difference in mental alertness (as measured by video game performance) before eating tryptophan versus after eating tryptophan?
