You have been asked to test a new formula for an energy drink against the old formula. You gather two groups. Group 1 is given the new formula. Group 2 is given the old formula. You ask both groups to rate their energy level on a scale from 0 to 10, with 0 meaning "very tired" and 10 being "very energetic." The descriptive statistics are below.Does the new formula increase energy level ratings?Test at= .05
