2. In Fig. 6.e2a we are given the spatial arrangement of 7 data points together with the corresponding data values, as well as 1 point where an estimate is sough (denoted as "?"). The distances between the data and the estimation point are also shown in Fig. 6.e2b. Using the GID technique derive estimates at location "?" for p -1 and 5.
