Paired T-Test and CI: SNEWS (dalam kelvin), SN1604 (dalam kelvin)
Paired T for SNEWS (dalam kelvin) - SN1604 (dalam kelvin)
N Mean StDev SE Mean
SNEWS (dalam 5 15294634 173719 77690
SN1604 (dala 5 15284058 173495 77589
Difference 5 10577 24250 10845
95% CI for mean difference: (-19535, 40688)
T-Test of mean difference = 0 (vs not = 0): T-Value = 0.98 P-Value = 0.385
P > alpha, terima H0 yang artinya pembacaan supernova (inti panas matahari) dengan menggunakan metode SNEWS TIDAK BERBEDA NYATA dengan menggunakan metode SN1604

Regression Analysis: Absorbansi versus Konsentrasi
The regression equation is
Absorbansi = - 0.0037 + 0.187 Konsentrasi
Predictor Coef SE Coef T P

Total 5 0.44645
Correlations: Konsentrasi, Absorbansi
Pearson correlation of Konsentrasi and Absorbansi = 0.997
P-Value = 0.000
Mendekati 1, sehingga antara konsentrasi dan absorbansi dalam pengamatan larutan NH3-N ada keterikatan yang sangat erat. apabila konsentrasi naik, maka absorbansi pun akan naik.
Regression Analysis: Absorbansi versus Konsentrasi
The regression equation is
Absorbansi = -0.0037049 + 0.186898 Konsentrasi
S = 0.0251822 R-Sq = 99.4 % R-Sq(adj) = 99.3 %
