For this problem, you can use the volume of a prism equation:
V=Bh
Where B is the area of the base and h is the height.
So to solve this problem, all you have to do is mutiply 44 square cm by 22 cm.
44 square cm • 22 cm = 968 cubic cm

Answer: B. ![H_0:p_1=p_2](https://tex.z-dn.net/?f=H_0%3Ap_1%3Dp_2)
![H_a:p_1>p_2](https://tex.z-dn.net/?f=H_a%3Ap_1%3Ep_2)
Step-by-step explanation:
Let
be the proportion of all U.S. adults that smoked in 1995. Let
denote the proportion of all U.S. adults that smoked in 2000.
Objective for the study : Whether the proportion of U.S. adults that smoke declined during the 5-year period between the samples.
i.e. ![p_1>p_2](https://tex.z-dn.net/?f=p_1%3Ep_2)
Alternative hypothesis
is the statement containing population parameter that shows there is significant difference between the groups being tested.
⇒ ![H_a:p_1>p_2](https://tex.z-dn.net/?f=H_a%3Ap_1%3Ep_2)
Null hypothesis
is the statement containing population parameter that shows there is no significant difference between the groups being tested.
⇒ ![H_0:p_1=p_2](https://tex.z-dn.net/?f=H_0%3Ap_1%3Dp_2)
Hence, The hypotheses to test in this problem are
![H_0:p_1=p_2](https://tex.z-dn.net/?f=H_0%3Ap_1%3Dp_2)
![H_a:p_1>p_2](https://tex.z-dn.net/?f=H_a%3Ap_1%3Ep_2)
Hence, the correct answer is B. ![H_0:p_1=p_2](https://tex.z-dn.net/?f=H_0%3Ap_1%3Dp_2)
![H_a:p_1>p_2](https://tex.z-dn.net/?f=H_a%3Ap_1%3Ep_2)
