Here are six measurements of the electrical conductivity of an iron rod. 10.02 9.83 9.99 10.10 10.15 10.05
The iron rod is supposed to have conductivity 10.1. Do the measurements give good evidence that the true conductivity is not 10.1?
The six measurements are an SRS from the population of all results we would get if we kept measuring conductivity forever. This population has a Normal distribution with mean equal to the true conductivity of the iron rod and standard deviation 0.1. Use this information to carry out a test, following the four-step process.
A) SOLVE: Assume that we have an SRS from a Normal population. Calculate the test statistic. (Round your answer to two decimal places.)
z=
B) SOLVE (continued): What is the P-value for the test? (Round your answer to four decimal places.)
z=
