WebThe P -value is therefore the area under a tn - 1 = t14 curve to the left of -2.5 and to the right of the 2.5. It can be shown using statistical software that the P -value is 0.0127 + 0.0127, or 0.0254. The graph depicts this visually. Note that the P -value for a two-tailed test is always two times the P -value for either of the one-tailed tests. WebThe P-value is the significance level of α=0.01, so the null hypothesis. There is evidence to support the claim that the proportion of people over 55 who dream in black and white is …
