4 The pre-release material contains data for percentage employment rates in different areas
of England.
The diagram shows percentage employment rates between 2008 and 2022 for the North West of
England and the South East of England.

(a) Use your knowledge of the pre-release material to explain whether Series 1 (the lower
time series) or Series 2 (the upper time series) represents the data for the South East of
England.
[1]
A student uses the LINEST function to model the data for Series 2.
(b) Assuming that a straight line model is reasonable, use your knowledge of the pre-release
material to explain whether it would be appropriate to use this model to calculate an
estimate of the percentage employment rate in Cornwall, in the South West of England, in
2011. [1]
