11. Investigators at the U.S. Department of agriculture wished to compare methods of determining the level of E. coli bacteria contamination in beef. Two different methods (A and B) of determining the level of contamination were used on each of ten randomly selected specimens of a certain type of beef. The data obtained, in millimicrobes/liter of ground beef, for each of the methods are show in the table below. Method Specimen 4 5 1 3 6 2 A 22.7 23.6 24.0 27.1 27.4 27.8 B 23.0 23.1 23.7 26.5 26.6 27.1 7 8 35.2 34.4 33.2 35.0 9 40.4 40.5 10 46.8 47.8 Is there a significant difference in the mean amount of E. coli bacteria detected by the two methods for this type of beef? Provide a statistical justification to support your answer.
