(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
