of that variable on zinc. The test for whether differences occur "Before" versus "After" is <br />found in the t-test for the variable `After'. The T value and the P value will be reported. <br />The P value is a measure of the believability of the hypothesis that uo effect on Y is <br />caused by that X. A value for P smaller than 0.05 (5%), will be evidence that the <br />"Before/After" variab]e does affect the values for Y. A P value larger than 0.05 for After <br />would indicate that there are no differences in zinc concentrations between the time <br />periods. <br />SGC will complete a comparison of expected water quality and baseline water quality at <br />A-72 and will submit the analysis (including the data, regression equation and T and P <br />values for the coefficients) to the Division. This comparison will be used to evaluate the <br />application for tenninatiou. <br />Appendix A <br />11 <br />232565 <br />
