A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival 1
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not

A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups .

A = 12 B = 11 a = 12 b = 11
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 7

Effluent Toxicity Statistical Results - Chronic Pass/Fail Date: 04/20/18
Facility: SOUTH HARNETT CO.REGIONAL WWTP NPDES#: NC0088366 Pipe#: 001 County:HARNETT
Laboratory Performing Test: MERITECH LABS, INC.
Reduction: -0.38% CONTROL 34% Effluent
# Replicates 12 12
Female Live 12 12
Adult Male 0 0
Adult Dead 0 0
Adult Mortality 0.00% 0.00%
# Neonates 265 266
Mean # Neonates 22.083 22.167
Standard Deviation 1.730 2.250
Coefficient of Variation 7.833%
Fisher's Exact Test
A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.
Test Passes!

A = 12 B = 11 a = 12 b = 11
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 7

Fisher's Exact Test
A = 12
B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.

Wilcoxon Rank Sum Test
Rank Sum - Effluent Group(treatment) : 191 Control Group: 109
Mann-Whitney U = 113 .0 n1(treatment) = 12 n2 (control) = 12
The critical value from TABLE A.15 (0.01 Level of T) for the above n values:
Critical T = 109
191 > 109
The Sum of the Ranks of the effluent group is greater than the significant
value from the table. Therefore there is no significant difference between
the means of the effluent and control groups and the test passes.

A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8

Fisher's Exact Test
A = 12 B = 12 a = 12 b = 12
a/A = 1.00 b/B = 1.00
Success is: survival
Critical b value = 8
12 > 8
The test concludes that the proportion of survival is not
significantly different for the control and the effluent groups.

Lower PMSD bound determined by USEPA(loth percentile) =12%.
Upper PMSD bound determined by USEPA(90th percentile).30%.
Lower and upper PMSD bounds were determined from the 10th and 90th percentile,respectively,of PMSD data from EPA's WET Interlaboratory Variability Study(USEPA,2001a;USEPA,2001b).

innett's MSD value: 2.226 MSD= Minimum Significant Difference
ASO: 7.9 PMSD= Percent Minimum Significant Difference
PMSD is a measure of test precision. The PMSD is the minimum percent difference between the control and treatment that can be declared
statistically significant in a whole effluent toxicity test.
Lower PMSD bound determined by USEPA(10th percentile) =13%.
Upper PMSD bound determined by USEPA(90th percentile)=47%.
Lower and upper PMSD bounds were determined from the 10th and 90th percentile,respectively,of PMSD data from EPA's WET Interlaboratory
Variability Study(USEPA,2001a;USEPA,2001b). The lower PMSD bound represents a practical limit to the sensitivity of the test method and is
not a minimum acceptance criteria.

Dunnett's MSD value: 2.617 MSD= Minimum Significant Difference
PMSD: 9.0 PMSD= Percent Minimum Significant Difference
PMSD is a measure of test precision. The PMSD is the minimum percent difference between the control and treatment that can be declared
statistically significant in a whole effluent toxicity test.
Lower PMSD bound determined by USEPA(10th percentile) =13%.
Upper PMSD bound determined by USEPA(90th percentile)=47%.
Lower and upper PMSD bounds were determined from the 10th and 90th percentile,respectively,of PMSD data from EPA's WET Interlaboratory
Variability Study(USEPA,2001a;USEPA,2001b). The lower PMSD bound represents a practical limit to the sensitivity of the test method and is
not a minimum acceptance criteria.
