1.Measuring GDP (6pts): A simple economy has four industries:

? The agricultural industry sells $45 million in food products directly to households as well as $35

million to the steel industry, which turns the food into biofuel for their factories.

? The iron mining industry produces iron, all of which is sold to the steel industry. Total sales to the

steel industry are $200 million per year.

? The coke industry produces coke which is combined with iron to make steel. Total sales to the steel

industry are $45 million per year.

? The steel industry processes the iron and coke together to make steel. The steel industry sells $300

million to the auto industry to make cars per year. Assume another $50 million is sold directly to

consumers/households and companies to put up steel fencing around their properties.

? The auto industry uses steel from the steel industry as well as other inputs (that it creates on its own)

to sell $725 million in vehicles to the public.

A certain species of plant produces flowers which are either red, white or pink. It also produces leaves which may be either plain or variegated. For a sample of 500 plants, the distribution of flower colour and leaf type was: Red White Pink Plain 97 42 77 Variegated 105 148 31 (i) Test whether these results indicate any association between flower colour and leaf type. [6] (ii) A genetic model suggests that the proportions of each combination should be as follows: Red White Pink Plain 9/2 (1-3q)/2 Variegated 3q/2 (1-5q)/2 where q (0
