Question

The diameter of a ball was measured five times with the aid of a micrometer whose absolute error (Deltad_("inst"))= pm 0.01 mm. The results of measuring the diameter of the ball are d_(1)=5.27 mm, d_(2)=5.30 mm, d_(3)=5.28 mm, d_(4)=5.32 mm and d_(5)=5.28 mm. Find (a) mean value of ball diameter (b) mean absolute error (c) result of measurement (d) relative error (e) persentage error.
