Ounces of milk, as measured in Exercise 16.19

Determine

(a) Whether the variable is measured at the nominal, ordinal, interval, or ratio level, and

(b) Whether it is continuous or discrete.

Data from exercise 16.19

Determine if the study is descriptive, experimental, quasi-experimental, or correlational.
A milk-processing plant had strict standards regarding how much milk went into each container. A quart container, for example, was supposed to contain no less than 31.5 ounces and no more than 32.5 ounces. Every day, quality control randomly sampled 100 quartcontainers, precisely measured their contents, and prepared a graph showing the distributionof amount per container.
