e.Interpret the result.

Fill in this statement by choosing the correct word:

We find evidence the average contamination is (higher, lower) after the new soap is used.

An investigation of the effectiveness of an antibacterial soap in reducing operating room contamination resulted in the accompanying table. The new soap was tested in a sample of eight operating rooms in the greater Seattle area during the last year. The following table reports the contamination levels before and azer the use of the soap for each operating room. Operating Room A B C D E F G H .5 9.0 10.3 11.2 8.1 6.3 11.6 4 7 4 8.5 8.1 6.1 3.4 Before 6.6 After 6.8 Click here for the Excel Data File At the 0.05 signicance level, can we conclude the contamination measurements are lower after use of the new soap? a.
