Question 34 • Statistics

An athletic trainer would like to estimate how many additional calories are burned when completing a high-intensity interval training (HIIT) workout for 30 minutes rather than doing yoga for 30 minutes. A group of 30 volunteers is randomly assigned to take a 30 -minute HIIT class or a 30 -minute yoga class, and each volunteer wears a calorie-counting armband. Here are summary statistics and dotplots of the results.
