Which sampling method would most likely be used in a poll of voters regarding a referendum calling for a national gun control standardization? (a) use satisfied random sampling (b) use simple random sampling (c) use convenience sampling (d) use cluster sampling (e) use systematic random sampling

The sampling method would most likely be used in a poll of voters regarding a referendum calling for a national gun control standardization is that Stratified Random Sampling.  This method would use a strata or groups and  samples are to be picked up by the researcher randomly.

(A) Use stratified random sampling

Step-by-step explanation:

Since, the population include all the citizens of that country so it is quite large data and working on this population is quite time taken and costly. Thus, Sample must be taken and it must be taken by appropriate sampling method.

 Here Stratified Sampling is used because by this sampling method peoples of every state, every cities, every village can be taken without much expense and in less time.

Further,

If the samples from the population are chosen randomly, where each and every unit has an equal chance of selection in a sample. This type of sampling is called Simple Random Sampling.

If the observers collect the sample as his\her convenience, then this type of sampling method is called Convenience Sampling.

In Cluster Sampling the population is distributed into a distinct group (clusters) and one or more groups (clusters) are chosen as a sample.

In Systematic Sampling the selection of sample is taken by some criteria . Like he\she is taken every 7th unit as a sample from the population.

average rate of change is 1

Step-by-step explanation:

chose two points that are before x = 4

(0,1) and (1,2)

slope = (y₂ - y₁)/(x₂ - x₁)

         = (2 - 1)/(1 - 0)

         = 1/1

         = 1
