When prices typically increase over time, FIFO results in higher inventory values, lower cost of goods sold, and higher net income, while LIFO leads to lower inventory values, higher cost of goods sold, and lower net income. Conversely, when prices decrease, the effects are reversed, with FIFO showing lower inventory values, higher cost of goods sold, and lower net income, and LIFO exhibiting higher inventory values, lower cost of goods sold, and higher net income.

3. Let $ X_{1}, X_{2}, \ldots, X_{n} $ be iid according to a $ N\left(\mu, \sigma^{2}\right) $, where $ \mu $ is unknown but $ \sigma^{2} $ is known. Take the one-sample mean test of $ H_{0}: \mu=\mu_{0} $ vs. $ H_{A}: \mu=\mu_{A} $. Assume $ \alpha=0.05 $ and a large sample size n (say $ n \geq 100 $ ). This implies the critical value for this test is approximately 1.96. a. Derive the form to compute the power of this test. b. Calculate the power of this test when $ \mu_{0}=5, \mu_{A}=4.1, \sigma^{2}=9, \alpha=0.05 $, and $ n=100 $. c. Again, let $ \mu_{0}=5, \mu_{A}=4.1, \sigma^{2}=9 $, and $ \alpha=0.05 $. We would like our power to be equal to 0.90 . What would the sample size need to be to achieve this power.

(a) Find the velocity at time t. Recall that the acceleration of an object is a(t) = v'(t). Therefore, to find v(t) given a(t), the following relationship can be used. $\int a(t) dt = v(t)$ We are given a(t) = 2t + 4. Therefore, we have the following. v(t) = $\int (2t + 4) dt$ = + C
