The use of ocular micrometer and stage micrometer measurements

During the calibration of an ocular micrometer, two (2) stage micrometer divisions were observed to line up with ten (10) ocular divisions. If the graduation interval on the stage micrometer is 0.01mm, calculate:

1. The calibrated value of the ocular micrometer in micrometer (uM). 

2.The size of Pseudomonas aeruginosa which has occupied 5 ocular divisions.

    A new process has been developed for applying photoresist film to 125 mm silicon wafers used in manufacturing integrated circuits. Ten wafers were tested, and the following photoresist film thickness measurements were observed: 13.3987, 13.3957, 13.3902, 13.4015, 13.4001, 13.3918, 13.3965, 13.3925, 13.3946 and 13.4002 angstroms (1 angstrom = 1x 10- metre). The photoresist film process has shown from past results that the distribution is normal. Use a = 0.05 and s = .00391 a. Test the hypothesis that the mean...
