An education expert is researching teaching methods and wishes to interview teachers from a particular school district. she randomly selects ten schools from the district and interviews all of the teachers at the selected schools. does this sampling plan result in a random sample? simple random sample? explain.

No, It is a Cluster Sampling.

Step-by-step explanation:

Simple Random Sampling is the sampling when samples are chosen randomly, where each unit has an equal chance of being selected in a sample.

If the population is divided into a different group called cluster and clusters are selected as a sample then it is Cluster Sampling.

Here, since Expert is interviewing all of the teachers at the selected schools, so it is Cluster Sampling, not a Simple Random Sampling.

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

im pretty sure it would be 5 am, hope that , and give brainliest and guys if this is right then press the button and give 5 stars
