WebIn this video there was no critical value set for this experiment. In the last seconds of the video, Sal briefly mentions a p-value of 5% (0.05), which would have a critical of value of z = (+/-) 1.96. Since the experiment produced a z-score of 3, which is more extreme than 1.96, we reject the null hypothesis. WebWe need to find where our t-score of 2.289 fits in. I highlight the two table values that our t-value fits between, 2.064 and 2.492. Then we look at the two-tailed row at the top to find the corresponding p values for the two t-values. In this case, our t-value of 2.289 produces a p value between 0.02 and 0.05 for a two-tailed test.
