Step 1 of 2

Here we will have to comment on the precision and the accuracy of each tailor's measurements.

Given:

The measurements of the trousers made by tailors X, Y and Z in inches are given below, all have taken three measurements.

X (31.5, 31.6,31.4)

Y (32.8, 32.3, 32.7)

Z (31.9, 32.2, 32.1)

The true length is 32.0 inch.
