To determine the population to which the results can be generalized for each of the samples, we need to representativeness of each sample in relation to the population of interest. The population of interest in this case is the annual salary of teachers.a. A random sample of 100 teachers in the United States.- This sample is representative of the population of all teachers in the United States. The results can be generalized to the entire population of teachers in the United States.b. A random sample of 100 high school teachers in Michigan.- This sample is representative of the population of high school teachers in Michigan. The results can be generalized to the population of high school teachers in Michigan.c. A random sample of 100 high school teachers at an education conference.- This sample is representative of the population of high school teachers attending the education conference. The results can be generalized to the population of high school teachers at the conference.d. A voluntary response sample of 100 elementary school teachers in Michigan.- This sample is not representative of the population of elementary school teachers in Michigan because it is a voluntary response sample. The results can only be generalized to the subset of elementary school teachers who chose to participate in the survey.e. A convenience sample of 100 high school teachers at an education conference.- This sample is not representative of the population of high school teachers in general because it is a convenience sample. The results can only be generalized to the subset of high school teachers who were present at the education conference.In summary:a. All teachers in the United Statesb.
