As a a test of a new measurement process, 10 measurements are made on pieces of glass known to have conductivity 1. The average of the 10 measurements is 1.07.


Indicate whether 1 and 1.07 is a parameter or statistic and explain why.

I know 1.07 is a statistic. I understand the population = parameter and sample = statistic. I don't understand whether the "1" is referring to a population or just the 10 pieces.

"10 measurements are made on pieces of glass know to have conductivity "1."

is the "1" representing the population or just the 10 pieces/sample??

In this context, the value of "1" represents the known conductivity of the pieces of glass on which the measurements are made.

However, it's important to note that the term "population" typically refers to the entire group of individuals, objects, or events that you want to study, whereas "sample" refers to a subset of that population.

In this case, the statement mentions that 10 measurements are made on pieces of glass known to have conductivity "1." Based on this information, it seems that the value "1" is specific to the 10 pieces that were chosen for measurement, which would make it a sample statistic rather than a population parameter.

To further clarify, a population parameter would be a characteristic that describes the entire group of glasses in terms of conductivity. For example, if you were measuring conductivity for all pieces of glass in a manufacturing facility, the average conductivity of all the pieces in the facility would be a population parameter. However, if you only measured the conductivity of a subset of the glasses (in this case, 10 pieces), the average conductivity of just those 10 pieces would be a sample statistic.
