Answer 1

Type of data

The data which consist of values representing count or measurements is quantitative data and the data which consist of values that can be placed into non-numeric categories is qualitative data.

Interval scales are numerical scales in which intervals have the same interpretation throughout and it has no "true zero" i.e. zero doesn't mean absence. On the other hand ratio scale is an interval scale with an additional property of "true zero".

• Amount of water(oz) is numeric in nature and zero oz means no water. Thus it's quantitative and ratio level.
• Hours of sleep per night is countable and zero hour indicates no sleep. Thus it's quantitative and ratio level.
