An education publication claims that the mean expenditure per
student in public elementary and secondary schools is at least
$10,200. You want to test this claim. You randomly select 16 school
districts and find the average expenditure per student. The results
are listed below. At α = 0.01, can you say the mean expenditure is
different either way from the amount in the publication? Assume the
population is normally distributed.
