You are conducting a study of students doing work-study jobs on your campus. Among the questions on the survey instrument are:

A. How applicable is this work experience to your future employment goals? Respond using the following scale: 1=not at all, 2= somewhat, 3=very

(a) Suppose you take random samples from the following groups: freshmen,sophomores,juniors, and seniors. What kind of sampling technique are using (simple random,stratified,systematic,cluster,multistage,convenience)? 

(b) Describe the individuals of this study.

(c) What is the variable for question A? Classify the variable as qualitative or quantitative. What is the level of measurement?

(d) What is the variable for question B? Classify the variable as qualitative or quantitative.What is the level of the measurement?

(e) Is the proportion of responses ''3=very'' to question B a statistic or a parameter?
(f) Suppose only 40% of the students you selected fro the sample respond.

What is the non response rate? Do you think the nonresponse rate might introduce bias into the study?Explain.

(g) Would it be appropriate to generalize the results of your study to all work-study students in the nation? Explain
