问题如下：
Which of Olabudo’s observations of forecasting is correct?
选项：
A.Only Observation 1
B.Only Observation 2
C.Both Observation 1 and Observations 2
解释：
The confidence
level influences the width of the forecast interval through the critical
t-value that is used to calculate the distance from the forecasted value: The
larger the confidence level, the wider the interval.
Therefore,
Observation 1 is not correct.
Observation
2 is correct. The greater the standard error of the estimate, the greater the
standard error of the forecast.
为什么observation 1不对呢？
