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 and the standard deviation was The = 0.042. average of seven x= 3.16 replications of the second method was and the standard deviation was = 3.24 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?

Transcribed Image Text: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
and the standard deviation was
Sx
The average
of
seven
x = 3.16
= 0.042:
replications of the second method was
and the standard deviation was
= 3.24
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?
