A. STATE: What is the practical question that required a statistical test?

A.	Is there evidence that the true conductivity of the liquid is 10.1?
B.	Is there evidence that the true conductivity of the liquid is larger than 10.1?
C.	Is there evidence that the true conductivity of the liquid is not 10.1?
D.	Does this sample give a good estimate for the true conductivity of the liquid?

A.The practical question that required a statistical test is:

Is there evidence that the true conductivity of the liquid is 10.1?

B.The parameter is the true conductivity.
