travenon wants to find the answer to the question how much money does the average college professor make? he surveys 50 professors from the university in his hometown. which best describes whether or not the results of his survey would represent the responses from the entire population of college professors? the results do not represent the population because not all college professors actually responded. the results do not represent the population because the sample does not represent professors from different areas. the results represent the population because the sample contained college professors and the population is college professors. the results represent the population because he sampled a large number of professors.
The population of interest is all college professors, but the sample only consists of 50 professors from one university in his hometown. A sample needs to be representative of the entire population in terms of relevant characteristics. Since the sample is not from different areas and does not cover all college - professors, it is not representative.
