this is one problem thank you!

Suppose rN=6%,m1=10%, and b1=1.5. a. What is n, the required rate of return on Stock i? Round your answer to one decimal place. \% b. 1. Now suppose rFs increases to 7%. The slope of the SML remains constant. How would this affect ry and r ? I. Both r4 and n will remain the same. IL. Both rn and n will increase by 1 percentage point. III. in will remain the same and n will increase by 1 percentage point. IV. n will increase by 1 pergentage point and n will remain the same. V. Both rm and n will decrease by 1 percentage point. 2. Now suppose r ro decreases to 5%. The slope of the SML remains constant. How would this affect rM and n ? I. n will decrease by 1 percentage point and will remain the same. II. rM will remain the same and r will decrease by 1 percentage point. III. Both rm and n will increase by 1 percentage point: N. Both rM and n will remain the same. V. Both r and n will decrease by 1 percentage point. c. 1. Now assume that ras remains at 6%, but rm increases to 11\%. The slope of the SML does not remain constant. How would these changes affect n ? Round your answer to one decimal place. The new n will be %. 2. Now assume that ras remains at 6%, but ny fails to 9%. The slope of the SML does not remain constant. How would these changes affect n? Round your answer to one decimal place. The new ri will be
