dentify which type of sampling is​ used: random,​ systematic, convenience,​ stratified, or cluster. To determine customer opinio
Rudik [331]

Answer:

The type of sampling used is the Cluster sampling technique.

Step-by-step explanation:

- Random Sampling

In random sampling, each passenger would have an equal chance of being surveyed. If this particular scenario wanted to use random sampling, they would have used computer generated random passenger numbers and surveyed them, not just passengers all on the same bus picked randomly.

- Systematic sampling is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth passengers is picked to be sampled.

- Convenience Sampling

This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of passengers that they find.

- Stratified Sampling

Stratified sampling divides the population into groups called strata. A sample is taken from each of these strata using either random, systematic, or convenience sampling.

- Cluster sampling

Cluster Sampling divides the population into groups which are called clusters or blocks (the different buses). The clusters are selected randomly, and every element in the selected clusters is surveyed (each passenger on the selected buses, is surveyed!). Evidently the answer to the question!

Jim read 24 pages in 40 minutes on Tuesday and 18 pages in 24 minutes on Wednesday. Are the ratios of pages read to minutes on T
IRISSAK [1]

Answer: Not proportional


Step-by-step explanation:

Ratio of pages read by Jim on Tuesday to minutes =\frac{24}{40}=\frac{3}{5}=3:5

Ratio of pages read by Jim on Wednesday to minutes =\frac{18}{24}=\frac{3}{4}=3:4

But \frac{3}{5}\neq \frac{3}{4}

Therefore, the ratios of pages read to minutes on Tuesday and Wednesday are not proportional.
