The paper “Playing Active Video Games Increases Energy Expenditure in Children” (Pediatrics [2009]: 534 – 539) describes a study of the possible cardiovascular benefits of active video games. Mean heart rate for healthy boys ages 10 to 13 after walking on a treadmill at 2.6 km/hour for 6 minutes is known to be 98 beats per minutes (bpm). For each of 30 boys, heart rate was measured after 15 minutes of playing Wii Bowling. The resulting sample mean and standard deviation were 101 bpm and 15 bpm respectively. 2.1 Does the sample provide convincing evidence that the mean heart rate after 15 minutes of Wii Bowling is different from the known mean heart rate of 98 beats per minute? Use the p-value method with α = 0.01
