Tom has a meter stick which is marked off in centimeters (cm). he measures a distance three (3)
times and gets measurements of: 11.52m, 11.51m, and 11.51m. a later calibration of the stick
shows it to be actually 1.001m long (1mm too long). tom's friend bill also has a meter
stick but
it's marked off in millimeters (mm). he measures the same distance three times also, and gets:
11.452m, 11.451m, and 11.451m. a later calibration of his stick shows it to be 1.05m long (5 cm
too long)
a.
whose measurements are more precise, tom's or bill's?
b. whose measurements are more accurate?
