Question Find the appropriate rejection regions for the large-sample test statistic z in these cases. (Round your answers to two decimal places. If the test is one-tailed, enter NONE for the unused region.) (a) A right-tailed test with α-0.05 (b) A two-tailed test at the 10% significance level Z >

Write the regression equation indicated by these results. The slope of the regression is? Is the slope coefficient significant? What % of the variation in height is explained by age? What will the height be in 8 years? As we use the equation to predict height using ages further in the future from our sample mean value for age, what happens to the confidence interval of our prediction? Use the following information to answer questions 1-6. We're still trying to make money growing hybrid poplars for bioenergy and we wish to predict what the height of these poplars will be at a given age. To do this we regress height on age based on sample data using an Excel tool at a 95% confidence level and get the following results: x variable 1 coefficient = 4.54 y intercept coefficient = -1.32 x variable 1 p_value = 0.0510 y intercept p_value = 0.0044 R2 = 0.636 SE of regression = 9.56

Two long straight wires carrying conventional current I are connected by a three-quarter-circular arc of radius R (see the figure). (The rest of the circuit is far enough away that it contributes little magnetic field in this region.) Electric fields are also present in this region, due to charges not shown on the drawing. An electron is moving to the right with speed v as it passes through the center C of the arc, and at that instant the net electric and magnetic force on the electron is zero. Part 3 If the current is 7 A, the radius of the loop is 0.034 m, and the speed of the electron is 6.7 × 105 m/s: (c) What is the magnitude of the magnetic field at the center C, due to the current I? |B⇀|= T Part 4 (d) What is the magnitude of the electric field at the center C? |E⇀|= N/C Radius R 1 C. Electron 14

Please answer Q4 (7) A satellite in geosynchronous orbit 37,000km above the Earth's surface transmits sinusoidal EM waves of frequency 12GHz uniformly in all directions, with a power of 5.0 kW. a) What is the intensity of these waves as they reach a receiver at the surface of the Earth directly below the satellite? b) What are the amplitudes of the electric and magnetic fields at the receiver? c) If the receiver is circular in shape and an absorbing panel measuring 100.0cm in diameter oriented with its plane perpendicular to the direction the waves travel, what average force do these waves exert on the panel? Is this force large enough to cause significant effects? [Note: to quantify significance consider the approximate mass of such a panel in a practical situation] d) What is the force produced by the sun on this same receiver? Assume that the intensity of the sun at the Earth is 1.4 kW/m2. [Total: 15 marks]

The time to deliver packaged containers by a logistics company is found from samples of size 9. The mean and standard deviation of delivery times is estimated to be 168 hours and 18 hours, respectively. a) Calculate the 2o control limits for the average delivery time. b) Calculate the 30 control limits for the average delivery time. c) Based on the 30 control limits, what is the probability of a Type I error? d) If the mean delivery time shifts to 180 hours, what is the chance of detecting the shift on the first sample following the shift? (given the 30 control limits found above) e) Calculate the ARL for a shift of the average deliver time to 180 hours. f) On average, how many samples will be required to detect the change to 180 hours?

Eight point particles with charge q are located at the vertices of a cube with side a as shown in the figure. We will call P the point located in the center of the face of the cube that lies on the plane y = a (see figure). a) Determine the electric field produced at point P by the four charges located at y = a. b) Find the electric field at P produced by the charge located at the origin. c) Calculate the total electric field at point P Р a X

Please do parts B, D, E, H, and I Part 1: The United States and Canada are trade partners. Each country has a zero current account balance and is operating in long-run equilibrium. Assume that inflationary pressure causes the price level in the United States to rise relative to Canada. (a) How will the change in the price level in the United States affect: U.S. demand for Canadian goods and services? net exports of the United States? Explain. (b) Illustrate the impact of the change you identified in part (a) on a fully labeled AD–AS model for the U.S. economy. Use arrows to indicate any changes in AD, real GDP, and price level. (c) Ceteris paribus, will Canada's national income increase, decrease, or remain the same? (d) On side-by-side and fully labeled foreign exchange market graphs, illustrate the impact of the change in relative inflation on supply of the U.S. dollar (USD) and on demand for the Canadian dollar (CAD). Use arrows to indicate the change in the equilibrium exchange rate for each currency. Part 2: Japan and China are trade partners, each with a current account balance of zero. The government of Japan increases taxes for all businesses in Japan. As a result, Japan’s real income falls. (e) On a fully labeled foreign exchange market graph, illustrate the impact of Japan's decrease in real income on the Japanese yen (JPY) with the price in terms of the Chinese renminbi (RMB). (f) Based on your response to part (e), has the Chinese renminbi appreciated or depreciated? (g) Assume the new exchange rate is 20 yen per 1 renminbi. Calculate the price of yen in terms of renminbi. Part 3: Respond succinctly and precisely to each of the following scenarios. Hint: these are beginning with a currency value change; start from there, and do not consider what caused the change. (h) The European Union and Brazil are trade partners. Brazil's currency, the real, appreciates relative to the European Union's euro. Ceteris paribus, how will this change affect: Brazil's net exports? Explain. the capital and financial account of Brazil?
