How to calculate p-value from t

WebP-Value = P (z ≥ 2.09) We have to look at the value of 2.09 in the Z table. So, we have to look at -2.0 in the z column and the value in the 0.09 column. Since the normal distribution is symmetrical, the area to the right of the curve is equal to that on the left. So, we get the P-Value as 0.0183. P Value = 0.0183 Web10 mei 2024 · Then, t = -0.113 For t-Test we look into the t table to find the p-value, the degree of freedom (df) is n-1, i.e., 49 and we look for a value in row 49 to be equal or greater than t, and obtain the corresponding y value to get p-value to be roughly 45%.
