Suppose a study of 196 randomly sampled privately insured adults with incomes over 200% of the current poverty level is to be used to measure out-of-pocket medical expenses for prescription drugs for this income class. The sample data are in the file Drug Expenses. Based on the sample data, construct a 95% confidence interval estimate for the mean annual out-of-pocket expenditures on prescription drugs for this income class. Interpret this interval.
NonAromatic
Molecules or compounds that do not contain a ring of continuously overlapping p orbitals, thus lacking the stability associated with aromatic systems.
π Network
An extended system of π bonds in a molecule, which can involve multiple atoms contributing p orbitals for delocalized electron sharing.
Cyclobutadiene
A highly reactive, four-carbon cyclic diene that is unstable at room temperature, interesting for its peculiar electronic properties and symmetry.
1,3-Butadiene
A simple conjugated diene with the formula C4H6, important as a monomer in producing synthetic rubber.
