Hi there, I was wondering if someone could help me figure out how to make a pie chart and a bar graph for this math problem please.

At the University of Twin Peaks, the number of males and females in various major fields of study are as follows:

Social work--Males--20, females--80

Humanities--Males--40, females--40

Business--Males--60, females--50

Education--Males--90, females--90

Nursing--Males--10, females--90

a. Construct a five-slice pie chart for the different female majors. Do the same for the males.

b. Construct a bar graph like Figure 2.2(a) on page 39 for all males, broken down by major. Do the same for the females.

c. What level of measurement is the variable major? Justify your response.
