An industrial hygiene field data study was developed to collect representative, replicate air contaminant data, to test statistically the normality and independence assumptions, and develop corrective procedures for a compliance/noncompliance decision procedure when assumptions were inappropriate. Iron-oxide (1332372), total respirable dust, carbon-monoxide (630080), and toluene (108883) contaminants were sampled. Replicate data was collected using three personal sampler sets worn by volunteer workers. Results were adequate to conduct normality and independence investigations. The normality test indicated that, except for 8 hour iron-oxide samples, the normality assumption could not be rejected at the 5 percent significance level. The tests for independence based on pooled sample covariance indicated that the samples were uncorrelated. The authors conclude that the field data analyzed cannot be used to reject the normality and independence hypothesis.
