A researcher invited a sample of college students to a lab at 1:00 P.M. to take an attentional control test called the Stroop, in which color names are presented in different colors. After finishing the Stroop test, each student wrote down what foods they had consumed in the previous hour, and the researcher figured out how many calories each student had eaten. Please answer the following questions and provide as much detail as possible in your responses:

Person	Stroop test score (seconds to complete)	Calories consumed at lunch
A	100	550
B	120	200
C	150	210
D	80	600
E	85	750
F	90	400
G	60	575
H	120	325
I	110	350
