A manufacturer wants to assess if her new weight-loss cat food is effective. She has two groups of 20 adult cats that are overweight. 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.
