If all you are interested in is the p-value, a quick way to calculate this is by entering the following syntax directly into a cell: =T.TEST(array1, array2,tails,type) Here, array1 refers to the first set of data (A1:A11 in the example at left), array2 is the second set of data (B1:B11), tails refers to whether you want to run a …

https://info.5y1.org/p-value-calculator-t-stat_1_51aa5a.html
The P-value provides a measure of this distance. The P-value (in this situation) is the probability to the right of our test statistic calculated using the null distribution. The further out the test statistic is in the tail, the smaller the P-value, and the stronger the evidence against the null hypothesis in …

We can’t just say that the estimated σˆ is sometimes 20% smaller than the true value, and sometimes 20% larger, so it all cancels out. It doesn’t, because σ doesn’t have a symmetrical distribution, but something derived from a chi-square distribution (which wehave not introduced yet). Confidence intervals, ttests, P values – p.16/31

- Independent samples - Pooled standard devation - The equal variance assumption . Last time, we used the mean of one sample to test against the hypothesis that the true mean was a particular value. One-sided test: Two-sided test: We also applied the idea of testing against a specific value to a proportion. After all, a proportion is just a mean of zeros (nos) and ones (yeses). In every one ...
