According to your textbook, statistical procedures are used to: a. determine if the control group was randomly assigned to the dependent variable b. determine if the experimental group was randomly assigned to the dependent variable c. determine if the observed differences in the dependent variables are due to the independent variable or to something else d. determine if the observed differences in the independent variables are due to the dependent variable or to something else

Amonopolist’s inverse demand function is p = 150 – 3q. the company produces output at two facilities; the marginal cost of producing at facility 1 is mc1(q1) = 6q1, and the marginal cost of producing at facility 2 is mc2(q2) = 2q2.a. provide the equation for the monopolist’s marginal revenue function. (hint: recall that q1 + q2 = q.)mr(q) = 150 - 6 q1 - 3 q2b. determine the profit-maximizing level of output for each facility. output for facility 1: output for facility 2: c. determine the profit-maximizing price.$

Four key marketing decision variables are price (p), advertising (a), transportation (t), and product quality (q). consumer demand (d) is influenced by these variables. the simplest model for describing demand in terms of these variables is: d = k – pp + aa + tt + qq where k, p, a, t, and q are constants. discuss the assumptions of this model. specifically, how does each variable affect demand? how do the variables influence each other? what limitations might this model have? how can it be improved?
