Question 12 This question is based on the case study for Chapter 5. My goal is to check if students have carefully studied this important case study. My Mosby (the owner of Mr. Tux stores) has requested his bank to re-structure the monthly loan payment to the bank because Group of answer choices Sales of Mr Tux exhibit a strong cycle Sales of Mr Tux exhibit substantial irregularity Sales of Mr Tux exhibit strong variation by month. Sales of Mr Tux exhibit a strong trend Question 13 Which of the following is the most difficulty time series component to predict? Group of answer choices Trend Cycle Seasonality Bias Question 14 Consider the following trend descriptions: i) Each year, sales increase by 1 million dollars ii) The first year sales increase by 1 million; during the second year the increase is only 80% over the previous year, i.e. 800000; during the next year it is again 80% over the previous year, i.e. 640000; etc. Based on the above information, which of the following statements is true? Group of answer choices Description i) indicates a damping trend Description i) indicates exponential trend Description ii) indicates an exponential trend Description ii) indicates a damping trend Description i) indicates an exponential trend Question 15 Suppose Nike sales are expected to be 1.2 billion dollars for the year 2012. If the January seasonal index for Nike is 0.98, what is a reasonable estimate for January 2012 sales revenue? Group of answer choices 0.098 billion 0.1 billion 2.18 billion 1.176 billion Question 16 1. By calculating the centered moving average, we remove the cyclical and irregular components of a time series. Group of answer choices This is an incorrect statement This is an incorrect statement because the purpose of moving averaging is to remove the trend This is a correct statement This is a correct statement because the purpose of moving averaging is to remove especially the cycle Question 12 This question is based on the case study for Chapter 5.
