Question With the gasoline time series data from the given table, show the exponential smoothing forecasts using = 0.1. Week Sales (1000s of gallons) 1 17 2 21 3 19 4 23 5 18 6 16 7 20 8 18 9 22 10 20 11 15 12 22 Applying the MSE measure of forecast accuracy, would you prefer a smoothing constant of = 0.1 or = 0.2 for the gasoline sales time series? Do not round your interim computations and round your final answers to two decimal places. = 0.1 = 0.2 MSE Prefer: 0.2 Are the results the same if you apply MAE as the measure of accuracy? Do not round your interim computations and round your final answers to two decimal places. = 0.1 = 0.2 MAE Prefer: 0.1 What are the results if MAPE is used? Do not round your interim computations and round your final answers to two decimal places. = 0.1 = 0.2 MAPE

Select three companies competing in the same product or service category and explain how does each differentiate and position itself in the market place. Assume you have a company and you need to do market research about your products or services, suggest how the marketing research process needs to be framed. discuss whether the business would be best advised to have someone do the research for you or should it have done by yourself. Describe the environmental forces that affect a company's ability to serve its customers? Discuss the recent change in the technological environment that impacts marketing. How it has affected behavior and how has it changed marketing. Define the marketing information system and discuss its parts? Outline the steps in the marketing research process and explain what is the most important and difficult process for the researcher?

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.

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?
