To test whether there is a difference in the interest rates paid by the two states
A bond analyst is analyzing the interest rates for equivalent municipal bonds issued by two different states. At _ = .05, is there a difference in the interest rates paid by the two states?
State A
State B
Sample size
80
70
Mean interest rate (%)
3.7
4.25
Sample variance
0.02
0.03
A) No, because the test value -0.02 is inside the interval (-1.96, 1.96)
B) Yes, because the test value 445.79 is outside the interval (-1.96, 1.96)
C) Yes, because the test value -21.11 is outside the interval (-1.96, 1.96)
D) Yes, because the test value -8.11 is outside the interval (-1.96, 1.96)
