3. Rubax, a U.S. manufacturer of athletic shoes, estimates the following linear trend model for shoe sales: Qt = a+bt+c1D1+c2D2+c3D3Where, Qt = sales of athletic shoes in the t-th quartert = 1, 2, . . . . , 28 [2011(I), 2011(II), . . . . , 2017(IV)]D1 = 1 if t is quarter I (winter); 0 otherwiseD2 = 1 if t is quarter II (spring); 0 otherwiseD3 = 1 if t is quarter III (summer); 0 otherwiseThe regression analysis produces the following results: Is there sufficient statistical evidence of an upward trend in shoe sales? explain Do these data indicate a statistically significant seasonal pattern of sales for Rubax shoes? If so, what is the seasonal pattern exhibited by the data? Using the estimated forecast equation, forecast sales of Rubax shoes for 2018(III) and 2019(II).

Chapter 01 Homework Suppose that Rosa is a diligent hard-working first-year college student. One Sunday, she decides to start the day by working through 300 practice problems to study for the statistics class. Using a table to track her progress throughout the day, she notices that as the hours pass, it takes her longer to solve the problems. Time 7:00 AM 8:00 AM 9:00 AM 10:00 AM 11:00 AM Total Problems Solved 0 120 210 270 300 Use the table to answer the following questions. The marginal, or additional, gain from Piper's second hour spent working, from 8:00 AM to 9:00 AM, is The marginal gain from Piper's fourth hour spent working, from 10:00 AM to 11:00 AM, is problems. problems. The following week, Piper's statistics faculty advisor gives her some advice. In all their years of teaching they claim to observe that working on 105 multiple choice questions boosts a student's test score by about the same amount as spending an hour reviewing lecture notes. For simplicity, assume students…
