Question

1. when performing an optical test, the mean, drift max, and standard deviation should be within which of the following limits?

a. mean: 0.9500 to 1.0500, standard deviation <0.0015, drift max <0.0280
b. mean: 2.000 to 5.5000, standard deviation <0.0015, drift max >1.5000
c. mean:0.9500 to 1.0500, standard deviation >0.0075, drift max >1.5000

Explanation:

For optical test limits, the correct range for mean is typically around 0.9500 to 1.0500 (not extreme like 2 - 5.5). Standard deviation should be small (e.g., <0.0015, not >0.0075) for consistent results, and drift max should be small (e.g., <0.0280, not >1.5). Option a matches these expectations.

Answer:

a. Mean: 0.9500 to 1.0500, Standard Deviation: <0.0015, Drift Max: <0.0280
