Extracted text: Question 3 Two methods have been developed to determine the nickel content of steel. In a sample of five replications of the first method on a certain kind of steel, the average measurement (in percent) was = 3.16 and the standard deviation 2 was s, = 0.042. The average of seven replications of the second method was y = 3.24 and the standard deviation was s, = 0.048. a) Determine if there is a difference in the mean measurements between the two method and explain the most likely assumption that could be made before solving this problem? b) What informed your choice of solution method?
