Answer to Question 1

Event S: Supports US policy in Iraq, Event F: Female.

US Policy in Iraq
Gender Support Doesn't Support Row Total
Female 0.2438 0.2862 0.53
Male 0.3762 0.0938 0.47
Column Total 0.62 0.38 1.00

P(F  S) = P(F  S) / P(S) = 0.2438 / 0.62 = 0.393

Answer to Question 2

Mean = 139.7, standard deviation = 38.46.
