In the plot below, the blue dots represent a training data set, with features $x1$ and $x2.$ The target value for each point in the data set is written next to the point in dark red. The

orange $x$ in the plot represents a point for which we want to make a prediction.

Using $kNN$ regression, with $k=3$ and using Euclidean distance as the distance function, what is the predicted value for point $x?($alternatives shown with $2$ significant digits$)$

$1\mathrm{.}3$

$1\mathrm{.}5$

$1\mathrm{.}6$

$1\mathrm{.}7$
