So this is going to be equal to 0.002. And what you'd do in any significance test is then compare your P-value to your level of significance. And so if you look at 0.002 and compare it to 0.01, which of these is greater?

Webb25 sep. 2024 · The smaller the p-value the greater the discrepancy: “If p is between 0.1 and 0.9, there is certainly no reason to suspect the hypothesis tested, but if it is below 0.02, it strongly indicates that the hypothesis fails to account for the entire facts. We should not be off- track if we draw a conventional line at 0.05”. . WebbAll levels except the first have p orbitals. d ORBITALS.
