A bond analyst is analyzing the interest rates for equivalent municipal bonds issued by two different states. At a = 0.05, is there enough evidence to conclude that there is a difference in the interest rates paid by the two states?
State A  Sample Size: 70, Mean interest rate: 3.6, Population variance: 0.04
State B Sample Size: 70, Mean Interest Rate: 4.0, Population Variance: 0.05



a. Yes, because the test value –11.16 is outside the critical region

b. Yes, because the test value –3.11 is outside the critical region

c. Yes, because the test value 124.44 is outside the critical region

d. No, because the test value –0.01 is inside the critical region
