i) Derive the technical coefficients matrix (3 marks)
ii) Determine the Leontief’s inverse matrix (12 marks)
iii) Compute the output level for each product if the final demand for product A increased by 2000 units, that of product C decreased by 1,000 units and the final demand for product B remained unchanged. (5 marks)

A regional hardware chain is interested in estimating the proportion of their customers who own their own
homes. There is some evidence to suggest that the proportion might be around 0.70. Given this, what
sample size is required if they wish a 90 percent confidence level with a margin of error of ± .025?
a) Consider a consulting firm in a particular city where past records show that on average 6 customers arrive daily to seek consulting services. The demand for consulting services in the firm is distributed according to a Poisson distribution. Calculate the probability of exactly 0, 1, 2 and 3 customers arriving for the consulting services.
