Group 1 receives two servings of her companies regular adult formula food, while Group 2 receives two servings of her new weigh-loss formula. The table below presents the weight loss the cats experienced over the duration of the experiment. Calculate a t value based on the two treatment groups. Report your t-value as an absolute value (ie, positive number) to 4 decimal places.   Sample ID Regular Weightloss 1 0 1 2 0 4 3 1 3 4 1 1 5 1 2 6 1 2 7 2 4 8 2 3 9 0 4 10 2 3 11 2 4 12 0 0 13 2 3 14 1 1 15 0 4 16 0 0 17 1 1 18 0 2 19 1 0 20 1 2
