Suppose a manufacturer conducts a study to determine the average retail price (p) being charged for his product in a particular market area, for the last month. (i) Is this variable: (a) discrete, random variable (b) discrete, deterministic value (c) continuous, random variable (d) continuous, deterministic number (ii) The manufacturer also wants to determine the size of the market for its product Consequently, he determines the number of units sold in the area within the past month (N). Is this variable: (a) Continuous random variable (b) Continuous deterministic variable (c) Discrete random variable (d) Discrete deterministic variable (iii) What would be a good estimate of the manufacturer monthly average profit, if the manufacturing cost for a unit is c: (a) N*p (b) N*(p-c) (c) 1/36 sigma_i = 1^36 N_i * (p_i - c) (d) 1/36 sigma_i = 1^36 N_i p - c
