question 130

True/False

A cell phone service provider has 14,000 customers. Recently, the sales department selected a random sample of 400 customer accounts and recorded the number of minutes of long distance time used during the previous billing period. The company analyst used Excel to sort these values in order from high to low. She then assigned the highest value a rank of 1, the next highest value a rank of 2, and so forth. These ranks would be considered to be ordinal data.

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.

AntiAromatic

Compounds that possess cyclic, conjugated systems with 4n π electrons, which destabilize the molecule and make it less stable than expected.

NonAromatic

A compound that does not fulfill the criteria for aromaticity, lacking a continuous ring of p-orbitals.
