... The “t Critical two-tailed” refers to a 5% significance, and we see that we would not reject at this level. In fact, this being a 2-tailed test, a p-value of 6.7% means that the lowest significance at which we would reject the Null Hypothesis would be twice this value, or 13.4% – an unusually high c ...
