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：
B is correct. The confidence level influences the width of the forecast interval through the critical t-value that is used to calculate the distance from the fore-
casted 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.
