## Elementary Statistics (12th Edition)

a) For a ratio set of data, there is an absolute $0$. In this case, there is an absolute 0, hence the data set's level of measurement is ratio. b) This data is a number of words, so it can only consist of integers. 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.
