Final answer:
The question lacks sufficient data to calculate the forecasted Time Period 14 value for Requests using Holt-Winter's method, as the method demands a series of data points and details on seasonal variations.
Option 'b' is the correct.
Step-by-step explanation:
The student is asking for the forecasted Time Period 14 value for Requests using Holt-Winter's method, but unfortunately, the provided data in the question does not give us enough information to perform time series analysis or use Holt-Winter's method.
Holt-Winter's method takes into account seasonal variations as well as trends, and it requires a series of data points across different time periods.
For a correct and reliable forecast using this method, we would need the actual number of requests for the previous time periods, as well as details on any seasonal pattern within the data. Without this information, we cannot accurately calculate the forecasted value.
