Have you gotten the anwser? I been trying am so sorry I can’t get it
Answer:
1986 is the base year. so, the CPI of the base year is always 100%.
Option A
The value of $100 in 1993 would be = ($100/CPI of 1986) * CPI of 1993
= ($100/100) * 135
= $135
So, Option A is true.
Option B
$100 in 1992 would have been worth in 1986: ($100/CPI of 1992) * CPI of 1986
= ($100/120) * 100
= $83.33
So, Option B is false.
Option C
$100 in 1991 would have been worth in 1986: ($100/CPI of 1991) * CPI of 1986
= ($100/110) * 100
= $90.91
So, Option C is false.
Option D
The value of $100 in 1992 would be: ($100/CPI of 1993) * CPI of 1992
= ($100/135 * 120
= $88.89
So, Option D is false.

Answer:
B. they involve the use of expert judgement do develop forecasts
Explanation:
A time series is a series of events that is spaced equally in time. It is a statistical technique used to identify a time based trend of events and them make forecast using data from the trend/time series.
Time series requires certain processes which include discovering of a pattern in the historical data, projection of the historical data into the future, assumption that the pattern will remain the same(constant) as the time goes by, etc.
In time series method, since historical data is the point of reference for making a forecast, no expert judgements is required to develop forecasts. This is because once the data of the series from the past has been taken and a trend/pattern has been identified, that becomes the basis for future forecasts.
Cheers.
