Consider the following time series Quarter Year1 Year2 Year3
1 71 68 62
2 49 41 51
3 58 60 53
4 78 81 72
a. construct a time series plot. what type of pattern exist in the data
b. use the following dummy variables to develop an estimated regression equation to account for the seasonal effects in the data; Qtr1=1 if Quater 1,0 otherwise Qtr2=1 if Quater 2,0 otherwise Qtr3=1 if Quater 3,0 otherwise
c. compute the quarterly forecast for next year

answer: the answer is 127 degrees

c

step-by-step explanation:

there is vertical asymptote at x = 2 and x = 0

vertical asymptote occurs at the points where the denominator is 0. so we can say that

x = 2 occurs when there is a factor (x-2) in the denominator, and

x = 0 occurs when there is a factor "x" in the denominator

thus, the denominator of the equation would have "x * (x-2)", this is option c only. that's the correct answer.

i believe that the answer is

b. y-1=-2(x-4)

hope this !

1 and 0
