Solution

2.9) Nominal; (Explanation: Although the channels are represented by numbers, these
numbers are used for identification only and represent categories.)

2.10)Ratio; (Explanation: Percentages are considered a ratio scale, because \"0%\" is
viewed as a true/absolute zero.)

2.11)Ordinal; (Explanation: By ranking observations we create an ordinal scale.)

2.12)Interval; (Explanation: ACT scores, as well as most other test scores, are
considered an interval scale.)

2.13)Nominal; (Explanation: The states are categorical data.)

2.14)Ratio; (Explanation: The number of residents in each state is likely to be different.
For example, we can say that one state has twice as many people as another state.)

2.15) Ordinal; (Explanation: By ranking observations we create an ordinal scale.)
