Quizplus · Accepted Answer

The seasonal-irregular component values indicate that the seasonal component is present in the time series. To find the seasonal index for Quarter 1, we need to divide the average seasonal-irregular component value for Quarter 1 by the overall average seasonal-irregular component value. However, we do not have this data provided in the given information. Therefore, we cannot calculate the exact value of the seasonal index for Quarter 1.

However, we can make an educated guess based on the given options. Option B (1.18) is likely the best choice because it suggests that the average seasonal-irregular component value for Quarter 1 is higher than the overall average seasonal-irregular component value. This is in line with the common assumption that Quarter 1 is often associated with higher sales or activity levels, which would result in higher seasonal component values. The other options do not seem as plausible based on the limited information provided.
