So, we find the probability of the Z-score by going at +3 vertically and 0.05 horizontally. The probability of Z-score comes out to be 0.99886. Now, to calculate the p-value : P-value = 1 - Prob(Z-score) P-value = 1 - 0.99886. P-value = 0.001. Since, this is a 2-tailed test, we will multiply the the p-value by 2.To find the p-value, we can first locate the value -0.84 in the z table: Since we’re conducting a two-tailed test, we can then multiply this value by 2. So our final p-value is: 0.2005 * 2 = 0.401.To apply the T.TEST function to our dataset, we can use the following formula: =T.TEST(A2:A8,B2:B8,2,1) The above formula computes the p-value associated with a paired t-test for ranges A2:A8 and B2:B8, with a two-tailed distribution.
