6. A population is the entire group which you are studying. A sample is a subset taken from
a population. (LO1-3)
7. Discrete variables can assume only certain values, whereas continuous variables can
assume any value within a specific range. Examples will vary. (LO1-4)
8. The cell phone provider is nominal level data. The minutes used are ratio level. Satisfaction
is ordinal level. (LO1-5)
9. If you were using one store as typical of all of the stores selling electronic book readers in the mall
then it would be sample data. However, if you were considering all of the stores selling electronic
book readers in the mall, then the data would be population data. (LO1-3)

move. (LO1-3)

excellent. Based on these findings, we can expect a similar proportion of all customers to
feel the same way. (LO1-3)
