Professor Haveitall wanted to determine if the reaction time in people differs in their dominant hand versus their non dominant hand. To do this, he recruited 15 students. Each student was asked to hold a yardstick between the index finger and thumb. The student was asked to open the hand, release the yardstick, and then asked to catch the yardstick between the index finger and thumb. The distance that the yardstick fell served as a measure of reaction time. A coin flip was used to determine whether the student would use their dominant hand first or the non dominant hand. Results indicated that the reaction time in the dominant hand exceeded that of the non dominant hand. A) What type of experimental design is this? B) What is the response variable? C) What is the factor and the treatment? D) Identify the experimental units
