A dermatologist compared a new treatment for athlete’s foot (the experimental condition) to the standard treatment (the control condition). He tracked down 30 people with athlete’s foot on both feet and, for each participant, randomly assigned one foot to receive the new treatment and the other foot to receive the standard treatment. After three weeks of treatment, he measured the percentage of reduction in symptoms (the larger the number, the better the outcome). He found M_E = 88, M_C = 72, and s_D = 8.65. Analyze and interpret.
