Neurosurgery operative times ~ Several neurosurgeons wanted to determine whether a dynamic system (Z-plate) reduced the operative time relative to a static system (ALPS plate). Two professors from Arizona State University collected the data below, which gives the operative times, in minutes, for the two systems. Summary data is offered below:
