Three apprentice tailors (x, y, and z) are assigned the task of measuring the seam of a pair of trousers. each one makes three measurements. the results in inches are 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 in. comment on the precision and the accuracy of each tailor's measurements.

Explanation:

Average of reading of X = 31.5

Average of reading of Y = 32.6

Average of reading of Z = 32.06

True measurement is 32.0 so Z's is closest to the true value so Z is most accurate and Y is least accurate.

Since all of them have reading instrument which can read upto 0.1 so the precision of their measuring instrument is equal . Actually their measuring instrument appears to be same.so precision of their measurement is same.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
