The digital calliper measurements (mean and 95% confidence interval) are as follows:
BX = 58.68 ± 0.07 mm, BZ = 51.11 ± 0.09 mm, CX = 13.25 ± 0.05 mm and CZ = 12.84 ± 0.02 mm
(n = 20). Table 1 shows the mean value and the standard deviation obtained from the differences
between the true measurement and the scanned data.
