TABLE III

Statistical Analysis of the Probability of Producing a Leaking Crack in Aluminosilicate and Conventional Borosilicate Vials for Bump Check and Lensing Crack Replication Methods, Based upon Values in Tables II and V

Method	Glass	95% Two-Sided
			80% Two-Sided
				Median
		0.0250	0.1000	0.5000	0.9000	0.9750
Bump Check	Borosilicate	0.1349	0.1577	0.2060	0.2607	0.2918
Bump Check	Aluminosilicate	<0.0003	<0.0011	<0.0069	<0.0228	<0.0362
Lensing Crack	Borosilicate	0.5751	0.6228	0.7086	0.7854	0.8214
Lensing Crack	Aluminosilicate	<0.0005	<0.0021	<0.0138	<0.0450	<0.0711

Both 80% and 95% two-sided confidence intervals are calculated, though the intervals reported for the aluminosilicate vials represent upper bounds due to the absence of failures.
