Conduct the following test at the $ \alpha = 0.10 $ level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume that the samples were obtained independently using simple random sampling. Test whether $ p_1 \ne p_2 $. Sample data are $ x_1 = 30 $, $ n_1 = 255 $, $ x_2 = 36 $, and $ n_2 = 301 $. (a) Determine the null and alternative hypotheses. Choose the correct answer below. OA. $ H_0: p_1 = p_2 $ versus $ H_1: p_1 > p_2 $ OC. $ H_0: p_1 = p_2 $ versus $ H_1: p_1 \ne p_2 $ (b) The test statistic $ z_0 $ is . (Round to two decimal places as needed.) OB. $ H_0: p_1 = 0 $ versus $ H_1: p_1 = 0 $ OD. $ H_0: p_1 = p_2 $ versus $ H_1: p_1 < p_2 $

The window in a car has a thickness of 7 mm and a thermal conductivity of 1.4 W/mK. In order to prevent condensation, the inner surface temperature of the window must be kept above 15 °C. The outside air is 2 °C with a convection heat transfer coefficient of 50 W/m²K. The inside air is to be maintained at 20 °C with a convection heat transfer coefficient of 5 W/m²K. QUESTION #1 To accomplish this, it is proposed to use a thin electrical surface heater placed on the inner surface of the glass. Determine the rate at which heat that must be supplied in order to prevent condensation on the inner surface. QUESTION #2 An alternate solution to the condensation problem is to generate the heat uniformly within the glass. Determine the rate at which heat must be generated within the glass to prevent condensation. Compare your answer to Question 1, and determine which solution is more economical.

In comparing the absorption and variable cost methods, each of the following statements is true except: Only the absorption method may be used for external financial reporting. SG&A fixed expenses are not included in inventory in either method. When inventory increases over the period, variable net income will exceed absorption net income. Variable costing charges fixed overhead costs to the period they are incurred.

Problem 3 Blocks A and B are in contact with each other, at rest on a frictionless horizontal surface. A force of F = 18.0 N is applied as shown below. a) Determine the magnitude of the acceleration of the blocks and the contact force by Block B on Block A. The mass of block A is 4.00 kg and the mass of block B is 8.00 kg. b) Analyze the same problem, but now the Force is applied in the other direction on Block B. Determine the magnitude of the acceleration of the blocks and the contact force by Block B on Block A. The system is initially at rest, F = 18.0 N, the mass of block A is 4.00 kg and the mass of block B is 8.00 kg.
