1. Jenny wants to compare the number of weight people lose at her gym using two popular, non-overlapping weight-loss programs, Shred-It and Burn It. She randomly samples people who use each program and tracks their weight loss. Shred It Burn It Mean 10 kg 7 kg Standard deviation 3.5 kg 5.7 kg Number of people 35 35 Determine if the mean weight losses are significantly different for the two programs. Assume that all conditions have been met.
