In Study Design 2, Super Sneaker Company drew at random two groups of 15 high school students from the Halifax school district database. After obtaining their shoe sizes, the company manufactured 15 pairs of shoes for group 1, each pair with both soles constructed from material A, and 15 pairs of shoes for group 2, each pair with both soles constructed from material B. After 3 months, the amount of sole wear in each shoe was recorded in standardized units,...

Super Sneaker Company is evaluating two different materials, A and B, to be used to construct the soles of their new active shoe targeted to city high school students in Canada. While material B costs less than material A, the company suspects that mean wear for material B is greater than mean wear for material A. Two study designs were initially developed to test this suspicion. In both designs, Halifax was chosen as a representative city of the targeted market....
