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 after the use of the soap for each operating room. operating room a b c d e f g h before 6.6 6.5 9.0 10.3 11.2 8.1 6.3 11.6 after 6.8 2.4 7.4 8.5 8.1 6.1 3.4 2.0 1. state the decision rule for 0.05 significance level: h0: ? d ? 0; h1: ? d> 0. (round your answer to 3 decimal places.) reject h0 if t > 2. compute the value of the test statistic. (round your answer to 2 decimal places.) value of the test 3. at the 0.05 significance level, can we conclude the contamination measurements are lower after use of the new soap? 't reject/reject) /lower)after use of the new soap.
