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.

specific gravity is the density of a substance divided by the density of water. since (at standard temperature and pressure) water has a density of 1 gram/cm3, and since all of the units cancel, specific gravity is usually very close to the same value as density

so "c" is the answer

plz give brainliest

distance, luminosity, brightness, radius, chemical composition, and temperature
