Two different laboratories within a company further studied the morantel recovery percentage in shrimp when spiking with 10 ug/kg. The results from both labs are presented below. Shrimp Sample Laboratory 1 (ug/kg) Laboratory 2 (ug/kg) 108.82 113.36 2 101.59 107.47 3 102.17 109.01 a. A 4th shrimp sample was analyzed for morantel recovery percentage using laboratory 1. The result was 99.4%, can any of the data be thrown out using the Q and/or Tn test using the 95th percentile? b. Is there a statistical difference (90th percentile) between the two laboratories results in the study?
