The Z Score of the Sample Mean on the Distribution

question 34

Multiple Choice

The Z score of the sample mean on the distribution of means is:

• A)different from a normal Z score because an estimated population standard deviation is used
• B)smaller than normal due to the reduced variance in the distribution of means
• C)conceptually similar to creating a Z score from a raw score
• D)equivalent to the sample mean divided by the population variance

Definitions:

Chiral

Describes a molecule that cannot be superimposed on its mirror image, often resulting in different biological activities for each form.

Achiral

Lacking chirality; not having a non-superimposable mirror image.

Asymmetric Carbon

An asymmetric carbon, also known as a chiral carbon, is a carbon atom that is attached to four different groups, making its mirror image not superimposable on itself.

R or S

A system for specifying the configuration of chiral centers in molecules, based on the CIP (Cahn-Ingold-Prelog) priority rules.
