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 a = .05 Group 1 Group 2 New Formula Old Formula n1 = 17 no = 15 M1 = 9 M - 6 SS1 = 100 SS - 150 Calculate the INDEPENDENT-MEASURES t-test. Be sure to find the estimated standard error for the independent measures t-test first. You can do it! O +2.93 O -2.93 O +2.04 O -2.04
