% working 67 45 73 54 61
%Management 49 21 65 47 33
a. Develop a scatter diagram for these data with the percentage of women working in the company as the independent variable.
b. What does the scatter diagram developed in part (a) indicate about the relationship between the two variables?
c. Try to approximate the relationship between the percentage of women working in the company and the percentage of management jobs held by women in that company.
d. Develop the estimated regression equation by computing the values of b(o) and b(1).
e. Predict the percentage of management jobs held b women in a company that has 60% women employees.
