In a test of a new surgical procedure, five respected surgeons in FlatBroke Township were invited to Carver Hospital. Each surgeon was assigned two patients of the same age, gender, and overall health. One patient was operated upon in the old way, and the other in the new way. Both procedures are considered equally safe. The time (in minutes) to complete each procedure was carefully recorded. Use a right-tail test at α = .05.
Old Way (x) New Way (y)
The solution contains a paired t-test using the five step testing of hypothesis approach.
