Question 15

A researcher measures four microscope images of algae cells and records a magnification claim for each sample.

Sample	Length of image in $mm\text{mm}$	Actual length in $mm\text{mm}$	Recorded magnification claim
K	24	0.08	$×300\times300$
L	36	0.06	$×60\times60$
M	18	0.09	$×1.62\times1.62$
N	32	0.04	$×0.00125\times0.00125$
