Hello! I need help with c on this problem. Have I worked the rest of it correctly? Thank you!

1.Suppose in a five-team league, the winning percentages were as follows at the end of the season: Team A, 85% ; Team B, 55%; Team C, 45%; Team D, 35%, and Team E, 30%.

a)Computethe standard deviation of win percentage.

standard deviation = [((WPCT-.500)^2 / N]

= 0.294

b)Then suppose each team plays a 60-game schedule.Computethe "ideal" benchmark standard deviation of winning percentage based on equal playing strength.

0.5/G = 0.65

.294/.065 = 4.52

c)Computethe Noll-Scully ratio.
