Geophysical Modelling
Firstly, we may declare the thermal conductivity of the soil layers as constant value (2nd assumption). Indeed, if heat transfer is plane and steady, and if is not large (in our case ), one can make a reasonably accurate approximation using a constant average value of (Lienhard &Lienhard 2003, p. 51).

Statistical
The value of the correlation coefficient is -0.99, which represents a very strong negative correlation. Thus, it is concluded that there is a very strong linear association between the given data sets.

This answer is different from that in (c) because of the different value of σ used. In (c), the new σ is derived by adding up any 4 randomly selected books from the entire bookshop, whereas in (d), the new σ is simply four times the original σ, since 4 copies of the same paperback will typically be having the same
