Answer:

Cluster Sampling

Step-by-step explanation:

I cant be 100% sure as i am not in statistics, but by definition cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research (in this case its the phone book). Researchers then select random groups (three random pages) with a simple random or systematic random sampling technique for data collection and data analysis(interviews).

so that appears to be what is happening in this scenario.

Kelvin says that 22/30 is greater than 22/32 do you agree ? explain
kozerog [31]
When two fractions have the same numerators, the one with the smaller denominator is the greater fraction.

30 < 32 \Rightarrow \frac{22}{30} > \frac{22}{32}

So Kelvin is right.
