1.A study on women in upper management positions at U.S. firms was conducted. Monthly data (n=252 months) were collected for several variables in an attempt to model the number of females in managerial positions (y). The independent variables included the number of females with a college degree (x1), the number of female high school graduates with no college degree (x2), the number of males in managerial positions (x3), the number of males with a college degree (x4), and the number of male high school graduates with no college degree (x5). Determine which of the correlations reported in parts (a)-(d) results in a potential multicollinearity problem for the regression analysis. Answer it as "Yes" or "No".

(a)The correlation relating number of females in managerial position and number of females with a college degree: r= 0.983

____________

(b)The correlation relating number of females in managerial position and the number of female high school graduates with no college degree: r =0.074

________________

(c)The correlation relating number of males in managerial positions and number males with a college degree: r = 0.722

________________

(d)The correlation relating number of males in managerial positions and number of male high school graduates with no college degree: r=0.328
