b. Discrete
c. Everything has an equal chance of being selected.
Work Step by Step
a. For a ratio set of data, there is an absolute 0. In this case, there is an absolute 0, so the data set's level of measurement is ratio.
b. This data is a number of words, so it can only consist of whole numbers. Since there are only specific values that are valid, the data set is discrete.
c. Saying that the sample is a simple random sample means that after the population was chosen, all values had an equal chance of being selected.
