QUESTION 4
Suppose the following are the seasonal indices for the first three quarters of the year for a quarterly series:
Quarter
Seasonal Index
Q1
72.4
Q2
85.3
Q3
109.6
Remember that the seasonal indices should average 100 so you should be able to infer the seasonal index for Q4. Furthermore, suppose that the estimated coeffcients from a regression of the deseasonalized series on Time are given below:
Coefficients
Intercept
2,506
Time
71.3
If the original value of the series in a Q1 was 2,040, then what is the seasonally adjusted value? (please round your answer to 1 decimal place)

- Question 4 Listen Your Algebra 2 teacher collected data on the number of days each student was absent during a semester and their score, in percent, on the semester exam. The linear regression equation that models the data is ŷ=97.769-3.828x where x represents the number of days absent and y represents the exam score, in percent. The correlation coefficient is r=-0.707 and the coefficient of determination is =0.500. What are the appropriate interpretations of the slope, y-intercept, correlation coefficient, and coefficient of determination? **HINT** Slope: -3.828 y-intercept: 97.769 Correlation coefficient: r = -0.707 The rate the predicted semester exam score decreases for every stu- dent absence. The predicted % score a student will achieve based on having zero absences in a semester. a. correlation coefficient b. y-intercept c. slope The relationship be- tween the number of days a student was ab- sent and their corre- sponding exam score.arrow_forwardQuestion 21 Using the moving average can create some problems in the forecast. Which of the following is NOT a problem related to using the moving average? Increasing n smooths the forecast but makes it less sensitive to changes The forecast is created with very little data, likely not reflecting the requirements very accurately Requires extensive historical data O Does not forecast trends wellarrow_forwardQuestion 4 (a) With reference to your department or one in a company or organization that you are familiar with that is involved in generating forecasts of air cargo traffic, propose the purposes for which the forecasts can be employed. In the process of generating air cargo traffic forecasts, appraise the forces that will promote air freight growth and the constraints the air cargo market are likely to face.arrow_forward
