Kousei works at a company that produces sweetened condensed milk. If one or more samples exceed 10 bacterial CFU/mL (or CFU/g) the entire lot produced will be rejected. Kousei's boss, Kaori, wanted to know if the lot passed the FDA guidelines. The following bacterial counts were obtained after serial dilution and pour plating of the samples: Type of Dilutions plated 10-4 10-3 10³ Colony Plate 1 Plate 2 Plate 1 Plate 2 Plate 3 Plate 1 Plate 2 Plate 3 Plate 3 244 Bacteria 288 251 99 81 75 24 21 15 Based on the bacterial counts obtained, will the lot be rejected? Yes, because the computed CFU/mL is 2.5 x 10^7 O Yes, because the computed CFU/mL is 3.0 x 10^6 O No, because the computed CFU/mL is 3.0 x 10^3 O'No, because the computed CFU/mL is 2.5 x 10^3 OYes, because the computed CFU/mL is 3.8 x 10^5 O No, because the computed CFU/mL is 3.0 x 10^3 Information is lacking so CFU/mL cannot be computed

Question
Kousei works at a company that produces sweetened condensed milk. If one or more samples exceed 104 bacterial CFU/mL (or CFU/g) the entire lot produced will be rejected. Kousei's boss, Kaori, wanted to know if the lot passed the FDA guidelines. The following bacterial counts were obtained after serial dilution and pour plating of the samples: Type of Dilutions plated 10-4 10-³ 10'5 Colony Plate 1 Plate 2 Plate 1 Plate 2 Plate 3 Plate 1 Plate 2 Plate 3 Plate 3 244 Bacteria 288 251 99 81 75 24 21 15 Based on the bacterial counts obtained, will the lot be rejected? Yes, because the computed CFU/mL is 2.5 x 10^7 OYes, because the computed CFU/mL is 3.0 x 10^6 No, because the computed CFU/mL is 3.0 x 10^3 No, because the computed CFU/mL is 2.5 x 10^3 OYes, because the computed CFU/mL is 3.8 x 10^5 O No, because the computed CFU/mL is 3.0 x 10^3 O Information is lacking so CFU/mL cannot be computed
