A manufacturing company conducted a safety awareness program at 10 different production facilities. The following data represent the number of man hours lost over a one month period at each facility before and after the program. These data can also be found in the Excel file safety.xlsx.

Using α = 0.05, perform a hypothesis test to determine if the safety awareness program reduced the number man hours lost at the facilities.
