Calculate a p value in excel
How to Find a P-Value with Excel « Microsoft Office ...
Note: since the z value is too large to look up in the standard normal table, we need to use Excel to calculate this p-value. (Use the function: =2*(1-NORMSDIST(3.38))) On an exam, you could just say that the p-value is approximately equal to zero. 3. On the basis of a random sample, the null hypothesis

The p-value is the probability of obtaining a value of the test statistic as extreme, or more extreme than, the actual test statistic, when the null hypothesis is true. Example: Your z-statistic in a z-test is 3.162. To calculate the p-value, use the EXCEL function NORMSDIST. NORMSDIST(z) is the probability of obtaining a test statistic value ...

(b) Calculate the t-statistic: The p-value for the test vs. is. p-value = I found this using Excel. =TDIST(2.6335,98,2) = 0.0084. The p-value is less than 0.01, so we can reject the null hypothesis at the 5% significance level, and also at the 1% significance level. (c) The t-statistic is. The p-value for the test vs. is. p-value =
