Answer 1

To identify which of the listed sets includes only nominal numbers, we need to understand what nominal data is. Nominal data is categorical data that can be used to label variables without providing any quantitative value. Examples of nominal data include identifiers like names, phone numbers, room numbers, and zip codes.

Let's analyze each response:

1. **phone numbers, room numbers, zip codes** - All of these are nominal numbers as they are used for identification and do not have inherent numerical value.

2. **phone numbers, zip codes, costs of candy** - The costs of candy are quantitative data (ratio level), not nominal.

3. **zip codes, costs of candy, jersey numbers** - Again, costs of candy are quantitative, and jersey numbers could also be considered ordinal in some contexts but not perfectly nominal.

4. **zip codes, jersey numbers, weights of candy** - Weights of candy are also quantitative data.

Therefore, the correct set that includes only nominal numbers is:

**phone numbers, room numbers, zip codes**.
