    1 - D

    2 - C

    3 - A

    4 - E

    5 - B

    Step-by-step explanation:

    We have to match each key characteristic of a distribution with the concept it characterizes.

    1. Characterizes the spread of a group

    Here group refers to the population, thus the spread of population is given by population standard deviation

    D. Population standard deviation

    2. Characterizes the average value of a group

    Here group refers to the population, thus, the average value of population is given by population mean.

    C. Population mean

    3. Characterizes the average value of a subgroup

    Here the subgroup refers to the sample. The average value of sample is given by sample mean.

    A. Sample mean

    4. Characterizes the distribution of a subgroup

    The subgroup refers to sample. It is characterized by sample standard deviation.

    E. Sample standard deviation

    5. Characterizes percentages of a normal distribution

    z-values are used to characterize the percentages in a normal distribution.

    B. Z-values
