test for the difference between the mean cost of a city meal and the mean cost of a suburban meal, using α = 0.05.

choose an appropriate set of hypotheses, where mu 1μ1 is the mean cost of a meal in the city and mu 2μ2 is the mean cost of a meal in the suburbs.

a. h0 : h0: μ1 ≠ μ2 h1 : μ1 = μ2

b. h0 : μ1 = μ2 h1 : μ1 ≠ μ2

c. h0: μ1 > μ2 h1: μ1 = μ2

d. h0: μ1 = μ2 h1 : μ1< μ2
