Two instrumental methods were compared by measuring the concentration of calcium from the same gallon of milk 10 times each. If Fcalculated > Ftable for the two sets of calcium data, select ALL of the conclusion(s) that can be made. OThere is a significant difference in standard deviations for the two instrumental methods. O A"Case 2" t-test, comparing replicate measurements, should be used. There is not a significant difference in standard deviations for the two instrumental methods. A "Case 3" t-test, a paired t-test for comparing individual differences, should be used. OA"Case 1" t-test, comparing a measured result with a known value, should be used.

Q5. Two methods were used to measure fluorescence lifetime of a dye. The average result for Method 1 is = 1.382 ns with a standard deviation of s1 = 0.039 and n1= 7. The average result for Method 2 is = 1.346 ns with a standard deviation of s2 = 0.015 and n2= 5. Is there a difference between the two methods at the 95% confidence level using F test?
