Answer to Question 1

H0 : P = 0.50 (No preference), H1: P < 0.50 (less than 50 prefer The Big Bang Theory).
P(X  4  P = 0.5, n = 12 ) = 0.1208 + 0.0537 + 0.0161 + 0.0029 + 0.0002 = 0.1908
We fail to reject H0 of no evidence of preference for significance levels less than 19.08.

Answer to Question 2

D
