Question
Which of the following is true for an exponential smoother of = 0.8 relative to an
exponential smoother of = 0.2?
an exponential smoother of 0.8 gives more weight to the older data
an exponential smoother of 0.8 is closer to the slope of the line of best fit
an exponential smoother of 0.8 uses more data values in the moving average.
an exponential smoother of 0.8 gives more weight to the recent data.
2.
A multiple regression model contains 4 independent/explanatory variables and uses 40 observations to
estimate the model. What are the numerator and denominator degrees of freedom used to
determine the critical F- value?
4 and 40
4 and 35
4 and 46
3 and 39.

Explanation / Answer
a)an exponential smoother of 0.8 gives more weight to the recent data.
b)numerator degree of freedom =4-1=3
denominator degree of freedom =40-4=36
it should be 3 and 36 which is not the option ; you may go with 3 and 39
