16. A movie producer is bringing out a new movie, In order to map out his advertising, he wants to determine whether the movie will appeal most to a particular age group or whether it will appeal equally to all age groups. The producer takes a random sample from persons attending a pre-reviewing showing of the new movie and obtains the following result. Use x'-test to derive the conclusion, Age-groups Persons Under-20 20-39 40-59 60 and over Total Liked the movie 110 200 710 320 80 Disliked the movie 70 60 195 50 15 Indifferent 30 20 40 95 Total 400 100 200 300 1,000

We do not consider randomization. The relationship between a Nash equilibrium and an equilibrium in dominant strategies is that: an equilibrium in dominant strategies is a special case of a Nash equilibrium. O a Nash equilibrium is a special case of an equilibrium in dominant strategies. O they are the same. O a Nash equilibrium always exists, but an equilibrium in dominant strategies may not exist.
assume there are two types of workers, low- and high-ability, andlet 0 = 0.25 be the proportion of high-ability workers in the population. Assume their marginalproductivity and, therefore, their wages are wh = $20 and wl = $16, and that both types canuse college education to signal high ability. The cost of college education for low-ability workersis cl = $5 whereas the cost for high-ability workers is ch = $2. Consider the wage for both types of workers and the high-ability workers’ college cost, ch. For which values of 0 (the proportion of high-ability workers in the population) do the high-ability workers prefer the separating equilibrium over the pooling equilibrium? (a) Any 0 > 1/2(b) Any 0 < 1/2 (c) Any 0 < 3/4(d) Only when 0 = 1
