The owners of an industrial plant want to determine which of two types of fuel (gas or electricity) will produce more useful energy at a lower cost. the cost is measured by plant investment per delivered quad ($ invested /quadrillion btus). the smaller this number, the less the industrial plant pays for delivered energy. suppose we wish to determine if there is a difference in the average investment/quad between using electricity and using gas. our null and alternative hypotheses would be:
a. h0: (? e - ? g) = 0 vs. ha: (? e - ? g) = 0
b. h0: (? e - ? g) = 0 vs. ha: (? e - ? g) < 0
c. h0: (? e - ? g) = 0 vs. ha: (? e - ? g) > 0
d. h0: (? e - ? g) = 0 vs. ha: (? e - ? g) ? 0
