A Marketing Firm Asked a Random Set of Married and Single

A marketing firm asked a random set of married and single men how much they were willing to spend on a vacation. Is there sufficient evidence at $\alpha = 0.05$ to conclude that is there a difference in the two amounts?
$\begin{array}{lcc}\hline & \text { Married Men } & \text { Single Men } \\\hline \text { Sample size } & 70 & 70 \\\text { Sample mean } & \$ 880 & \$ 825 \\\text { Population variance } & 5700 & 7900 \\\hline\end{array}$

A) Yes, because the test value $3.95$ is outside the critical region $- 1.96 < z < 1.96$ .
B) Yes, because the test value $1.39$ is inside the critical region $- 1.96 < z < 1.96$ .
C) No, because the test value $0.28$ is inside the critical region $- 1.96 < z < 1.96$ .
D) No, because the test value $1.39$ is outside the critical region $- 1.96 < z < 1.96$ .
